New Red Sea nitrate remover?

[Jmck]

Ok, so as I was explained to by my LFS who is incredibly reliable. This stuff is made to be used daily and to grow bacteria to eat the nitrates and phosphates. HE said it is like vodka dosing but better.

the stuff is from red sea, its here

Red Sea Reef Care Program

and just click algae management.

What do you guys think? could this be a new thing that could really make our lives easier?

 

[little_fish]

Looks interesting, and it might have merit. I would like to see more information on how they came up with this stuff and tanks that have used just this for a long period of time.

But, they claim that it helps completely reduce to nitrogen gas, which unless you have an anoxic environment for that type of bacteria, simple cannot happen, no matter how well fed the bacteria are.

 

[Jmck]

Haha, I didnt understand some of what you just said. My LFS is currently running a tank without a sand bed on this and his skimmer.

I also decided that for the next few months ill use this stuff in conjunction with my skimmer and algae scrubber which I installed today. I will give you guys some results on how I think its going. May actually setup a small tank and just run it with this. Could be interesting. Thing is though, you have to dose everyday.

 

[little_fish]

What i mean is that the bacteria that convert NO3 to N2 must live in an oxygen free enviroment. If you dont have that, then you cant finish the nitrogen cycle.

Also, im kinda confused as to what they are trying to do. Are they trying to get bacteria to grow that will consume the the nitrogen products and phosphates? If they are it would be cool to do that with the phosphates, but the bacteria in your tank already use the nitrogen products so you shouldnt have to feed them. Or are they trying to get some specific type of algae present that will use them up?

 

[Jmck]

basically, I have been overrun with algae, and as my LFS explained it to me, this algae control will feed bacteria which will in turn eat nitrates and phosphates over a long period thus reducing and removing the nitrates and algae from the tank.

its meant to be good against cyano bursts and all different kinds of algae. So im basically trying to get my tank back under control and thinking this could be an interesting bit of chemistry.

 

[little_fish]

Interesting. Im not sure i buy that that, but lets see if it works on your tank!

Are you just using this product?

 

[Bifferwine]

I'm curious to see the results if you try it out!

It's the same principle that other additives use -- I had great success using Marine SAT in my 240 against an algae problem. All Marine SAT is is a bacterial additive. The bacteria consume the nitrates and phosphates more efficiently and readily than algae does, so they outcompete the algae, and the algae is eventually starved off.

 

[Jmck]

Yea thats the basic idea biff, so im hoping it will work. Looking forward to getting back to really taking control of this tank. Results wont be as conclusive because I just installed a scrubber, but will be interesting nonetheless.

 

[Reef Nutz]

Why pay for that? Vodka is alot cheaper. ? And we are basically talking about the same thing here.

 

[sen5241b]

In general you want to be very skeptical of all additives. Not too long ago I saw a link to a website that said they had a solution to tank maintenance so that you would never have to do a water change again. I go to the website and they want to sell me bio-balls.

 

[Jmck]

I don't think vodka is cheaper, this is 20 dollars a bottle but is mant to have 8 stages of carbon where vodka only covers one.

I am very wary sen, but my lfs has never pushed me in the wrong direction and has actually loat money refusing to sell me livestock ;) so I have some trust. But that is a bad example..... bioballs are the future!

I'm not sure I understand this..?? Carbon does not create bacteria that eats Trates.?? Vodka is much cheaper by volume compared to what you are going to be using. Bio Balls are the future?? They are Nitrate factories. ??

Vodka Dosing...Distilled!​

A Powerful Method for the Reduction of
Nitrates and Phosphates within the Reef Aquaria
by Nathaniel A. Walton (Genetics) and Matt Bjornson (Stony_Corals)​

The following information is provided for your consideration in regard to a topic that has been questioned by some of the best minds in the hobby. The goal of this column is to compact many threads interested in a particular discussion to a user friendly layout. The information contained in these articles is here to help educate and hopefully enhance the hobby, while helping you to make informed decisions on aquaria upkeep. The author(s) assumes no responsibility for any consequences that may arise from the use of this information.​

Introduction

While the concept of using an organic carbon source to reduce nutrients is not new to the hobby, it has recently gained considerable popularity. The number of carbon-source dosing threads on Reef Central (RC) currently reinforces this statement. These threads range in dosing of a single carbon source: vodka, sugar, or vinegar, to the combination of these three. Notably, the first major thread on RC for this subject was quite lengthy starting a couple of years ago ("Dosing vodka to bring down N and P"). This thread highlights the results of many aquarists that were achieved through careful vodka additions to their aquariums. Users note a dramatic decrease in nitrate and phosphate molecules, while others note increased coral coloration and clearer water. In this article we will discuss these potential benefits and give instruction on vodka additions while condensing the many threads on this subject into a more easily readable format.
Before starting, as with any project, there is a great deal of information that needs to be taken in and understood. While reading this if there is any question that is left unanswered please ask either someone on RC or in your local reef club. We ask that you read and ask questions until you have a firm understanding of the concepts behind vodka dosing. There are no dumb questions! And remember as with all good things it takes time, effort, and understanding to do a task properly.
What is an Organic Carbon-Source?

Carbon is the fourth most common element in the universe. It is unusual in nature as it has the ability to self-polymerize forming long chains. Carbon�s abundance combined with its ability to form a wide range of polymeric structures allows this molecule to form essential molecules found within all organisms. Carbon is found within your reef aquarium in abundance as inorganic bicarbonate. When these carbon molecules are incorporated into more complex forms within cells they are termed organic.
It has been reported that addition of certain organics can help enhance the appearance of the reef aquarium by reducing nitrates and phosphates. To do this, people have experimented with sugar, vinegar, and vodka. All of which are organic. Our discussion is focused on vodka addition. The reason vodka is used in comparison to other spirits such as whiskey, gin, or brandy is that vodka is more pure in composition than most other spirits because of its process of distillation. Other spirits are brewed with additives that enhance flavor. Vodka is not. Because it lacks additives it consists of mostly water and the organic compound ethanol. For this reason many feel vodka is a safer addition than other spirits by eliminating the possibility of adding other organic molecules that may act negatively within the reef environment.
Why dose Organic Carbon?

The main purpose to dose organic carbon is the reduction of excess nutrients in the reef aquaria. The two main nutrients reduced from organic carbon addition are nitrate and phosphate molecules (NO3 and PO4 respectfully). The reduction of phosphates, in turn, allows for enhanced calcification and growth of corals. Additionally, lower NO3 and PO4 have the added benefit of reduced nuisance algae, both bubble and hair. This observation has been reported numerous times by vodka users. The reduction in algae is the result of lower NO3 and PO4 within the water column and not a direct effect of ethanol addition. These potential benefits have lead some to add foreign organic carbon sources not usually found in the reef ecosystem to their tank. The organic compound most frequently used is ethanol (sold in stores as vodka).
The addition of vodka/ethanol is thought to increase bacterial biomass. For this, vodka addition would result in bacterial growth and reproduction. During this process nutrients in the water (including NO3 and PO4) are taken up for the formation of new macromolecules that are needed in cell synthesis and viability. Due to this rapid growth and reproduction, NO3 and PO4 can drop quickly from detectable levels by most test kits on the market. The increased biomass of the bacteria leads to a notable increase in skimmate production, removing more waste than without vodka addition. The increased skimmate is thought to remove the bacteria or bacterial biproducts that have assimilated the NO3 and PO4 within the water column leading to NO3 and PO4 depletion.
Many view organic carbon dosing as unnecessary as organic carbon isn�t thought to be limited in the reef aquarium environment since larger organic molecules are found within the water column at any given time. However, the amount of organic carbon that heterotrophic bacteria can utilize must be limited due to the reported benefits and observations on Reef Central from organic carbon dosing. This method is applicable for systems that have had the inability to effectively remove both NO3 and PO4 from their system. Stable systems that do not contain high levels of NO3 and PO4 may not benefit to any great extent by employing carbon source dosing.
Equipment - Skimmer, An Absolute Must!

Well if it sounds so great, why can�t I just start dumping vodka/organic carbon into my system? Before running to the liquor cabinet, the simple answer is overdosing can cause serious and detrimental effects to the reef system. To help circumvent this potential issue a dosing regimen along with some basic equipment is needed. The absolute must is the requirement for a powerful skimmer. People that have reported beneficial results using this method all have had strong skimmer and report a change in skimmate from a light brown to a strong odiferous black sludge. This makes a good skimmer a key requirement and important for two reasons:

1. Gas exchange. The increased bacterial biomass and growth will decrease your dissolved O2 levels in the water column. Too much vodka can result in a drastic decrease of O2 and can cause stress to your reef inhabitants, if not death.
2. Exporting bacteria/macromolecule mass. Vodka addition results in lower NO3 and PO4 levels. You will want to export the incorporated nitrogen and phosphates that you are cultivating by organic carbon dosing. Efficient skimming allows such removal.

J�rg Kokott, a key contributor to the original thread, recommended the use of ozone during the duration of vodka dosing to maintain high levels of dissolved O2 in the system. This decrease in dissolved O2 is indirectly observed in ORP meter readings after vodka addition. Though not an absolute requirement, as told from many RC participants, ozone may add an extra level of protection by increasing O2 levels during an overdose.
Gelbstoff, German for yellow matter, is reported to buildup in aquariums over time. Additions of vodka or other carbon sources have the potential to accelerate the yellowish water buildup from organics. To solve this problem, people have utilized ozonators to breakdown of the organic molecules responsible for resulting in yellowish water. Ozone is an attractive choice as it would not only breakdown the gelbstoff but will also add O2 to the water in case of an overdose. For people not interested in running ozone other solutions for this problem are the addition of granulated activated carbon or through regular water changes.

Dosing Instructions

These instructions will focus solely on using 80 proof vodka (40% ethanol by volume). They do not pertain to other organic carbon sources that are also currently used, including common table sugar (sucrose) and vinegar (sodium acetate). The dosing instructions below were as dictated by J�rg Kokott and have been used successfully by us.

1. Test your system�s NO3 and PO4 levels. Do not dose if you do not know this! We recommend good test kits that have some low level of sensitivity. This will be important later on to determining a maintenance dose regimen. During the initial dosing test often and adjust dosing parameters as needed as each tank�s requirement will be different. Dosing accuracy is of the utmost importance. A graduated measurement tool such as a syringe will come in handy. A journal of additions and test kit measurements is recommended.
2. Estimate your Net Water Volume (NWV) of your system. (Aquarium volume + sump + refugium + reactor volumes) � (live rock displacement). It can be difficult to accurately measure the amount of water being displaced by the live rock. If unsure of the volume of live rock we suggest taking 30% off your display tank�s Gross Water Volume. For vodka dosing there is absolutely no harm in underestimating the Net Water Volume and is recommended.

As an example, let us assume that your setup contains 100 Net Gallons.

1. The starting dosage is 0.1ml of vodka per 25 gallons (~100 liters) NWV daily continued for three days. For 100 Net Gallons, your dosage would be 0.4ml daily during this period. It has been suggested to cut the daily dosage in half and dose twice daily for more consistency.
2. Days 4-7, double the daily dosage to 0.2ml of vodka per 25 gallons NWV. Your example dosage would be 0.8ml daily during this period.
3. Each subsequent week add an additional 0.5ml of vodka regardless of aquaria volume. At this point your example dosage during week two would be 1.3ml daily. If you do not see nutrient levels decrease during this week, the following week add an additional 0.5ml for a daily dosage of 1.8ml daily.
4. When your NO3 and PO4 levels start to drop maintain the current dose. For example, if you were on week two when NO3 start to fall on 100 Net Water Volume you would add 1.3mL daily at this time for the continuing weeks until the NO3 becomes undetectable.
5. When your NO3 and PO4 levels drop near undetectable with your test kits cut your current dose in half. This will be your starting maintenance dose (if the levels drop during week 2 then the dose after reaching undetectable levels would be 0.65ml daily [1.3ml divide by 2]).
6. Continue to test for NO3 and PO4. If levels become detectable in the future increase your daily dose by 0.1ml increments per week until the levels start to decrease. If you maintain that dose the levels will eventually drop back to undetectable. This would become your new maintenance dose.

Throughout your dosing, observe your livestock daily to look for any signs of stress. If stress of any sort is noticed stop dosing, or at a minimum cut back by reducing your dose in half. If for some reason you cannot remember if you�ve added for that day skip it. It is better to accidentally miss a dose than add twice as much (a journal will keep this from occurring). Never double the dose for missing a prior day!

Common Questions

Bacterial Blooms - High additions of carbon sources at once are noted as production of slimy white strings upon rocks or in sumps that become noticeable a few hours to a day after addition. There is no clear evidence that this is detrimental to your tank. If this is observed dropping your dose by 50% will result in the disappearance of these strands. Additionally, these strands may have given rise to the notion of "bad bacteria". By this forum users mean pathogenic bacteria. But there has not been any documented evidence of such yet. If you happen to overdose your tank with an organic carbon dose, you will stimulate a bacteria bloom, this appears like a snowstorm in your tank. After a day, the tank will clear up. During this time people have reported mixed results on survival from this snowstorm. Stony_Coral has purposefully caused this on one tank and while ORP readings dropped, no loss of livestock was observed. However, people have mentioned loss of more delicate fish such as anthias during the visualized bloom. In general, a visible bloom will not occur if vodka is dosed as per the instructions above.
Bacterial Populations - Currently, it is unknown which bacterial populations grow with the addition of organic carbon. Some have suggested a single organic carbon source, such as vodka, results in monoculture or single specie growth. Due to this ideology, it has been increasingly common to dose multiple carbon sources as this may create additional bacterial diversity. Most likely, in any one organic carbon source addition there are several species that become dominant. However, it has not been decided whether diversifying impacts corals either beneficially or negatively.
Burnt tips - Some users of organic carbon dosing have reported the tissue loss at the ends of their SPS. These "burnt tips" have recovered once the user reduced the alkalinity levels within their tank to alkalinity levels closer to natural seawater (7-8 dKH), pictured below. Unfortunately, the root cause for this is not known.

Carbon Sources - Reduction in nitrates and phosphates can be accomplished with ethanol and vinegar with great efficiency. Other molecules that may aid in nutrient reduction are sugar, acetone, methanol, and isopropanol. We have not experimented with sugar though there are many threads on RC about this topic. The latter three have been called into question about the possible effects on health of the owner as well as the wellbeing of the aquarium inhabitants. For these reasons, we chose to describe ethanol addition as a means to decrease both nitrates and phosphate levels.
Coral Coloration / Paleness - With reduction of nitrates/phosphates SPS corals have been reported to increase in color pigmentation and have even been reported to pale over time. This is outside the scope of the article presented here. However, if looking for recommendations for additives that will reduce paleness and enhance SPS health check out amino acid addition as this has been reported to enhance coloration in a ULN (ultra-low nutrient) environment. If for any reason you experience coral bleaching, please stop vodka dosing!
Deep Sand Beds - People with Deep Sand Beds (DSBs) have reported issues with vodka dosing. These issues seem to be from increasing vodka additions over time without seeing a decrease in nitrate/phosphate levels. Users with DSBs that are failing to reduce nutrients efficiently may be experiencing a lack of nutrient decrease from the build up of organics within the DSB. If this were the case it would take more time to cycle out the nitrates within the system as there is now a hidden bed of organic waste that needs to be removed. Do not get discouraged or increase your dose irrationally as the vodka addition is working but not detectable as the DSB needs to cycle through completely before a reduction is observed. Keep adding vodka slowly until decreasing levels are detected. This may take months to achieve. Once there maintain that dose until nitrates start to decrease. At this point, it may be best to cut the dose in half and cut it in half again once undetectable is reached. Many people with DSBs who have reported issues increase vodka additions quickly and irrationally, leading to a detrimental overdose.
Feeding - A derivative of vodka dosing is the ability to increase feeding for fish or invertebrates without reducing water quality. Since the vodka is essentially removing the waste products (nitrates/phosphates) from the reef aquarium, addition of extra food is welcomed if not encouraged.
Old Tank Syndrome - Reef systems that have been running for longer than a year have reported vodka-dosing building up a thick sludge within some area of their reef. The thought is the buildup of organics and NO3/PO4 over time results in a high growth of bacteria from the addition of vodka. In tanks that are older, where detritus has built up, careful observation of the tanks state is needed. If thick sludge develops within the tank immediately reduce the dose by 50% and continue at that point until the sludge has disappeared and then slowly increase as per instructions laid out above.
Phosphate Removal / Granulated Ferric Oxide (GFO) - One of the most common questions is whether to use a phosphate removal material, such as GFO, with carbon dosing. GFO is useful in removal of phosphates from the water column. Essentially, by carbon source additions, the same net result is being achieved. It may even be counterproductive to run GFO while dosing an organic carbon source as both nitrate and phosphates need to be present for this to work properly. Therefore, it is not needed and not commonly recommended but some people continue to run phosphate reactors concurrently.
Water Clarity - Even without the use of either ozone or activated carbon, water clarity is said to improve dramatically with the vodka method. This has been stated by nearly everyone using this method and may be an indirect result of nitrate/phosphate removal from the water column. Dr. Jean Jaubert made similar claims of his plenum system, where nitrates and phosphates are also depleted and water clarity may be a result of this depletion.
Vodka Brand - One of the most common questions is which brand is the best. Honestly, it will make little difference on which brand is used. The most common response is to find the cheapest vodka brand and go with that. Do not use vodka that contains flavor additives such as raspberry or mango vodka. Additionally, industrial ethanol should not be used as a substitute as it contains denaturing agents that are toxic.
Summary

Vodka dosing has become a simple method for reduction of nitrates and phosphates that have plagued many reef aquarists. Here we have described a method for reduction of these nutrients by stimulation and promotion of bacterial growth through the addition of vodka. Though the underlying mechanism and actual bacteria populations are unknown the results are impressive for their ability to both rid the system of excess nitrates and phosphates.

He was being sarcastic about the bioballs...

 

[Jmck]

Hold on, I ask you, how is vodka cheaper than this? this is 20 dollars for 500 ml, how and we do not have vodka under 30 dollars here, infact, not sure if there are any under 40 here... and they are 700 ml. Edit: I did just see you use less vodka than this product and thus it would be cheaper, but if this products claims are right it is still more beneficial than vodka dosing. Hence the trial

So I dont see hwo it is cheaper. I didnt say carbon eats bacteria. This item is a food source for bacteria and I was just mimicking what Iw as told.

from your article, so the additive im using comes from 'carbon sources' as is what I said.


The main purpose to dose organic carbon is the reduction of excess nutrients in the reef aquaria.



So I dont think ive said anything outrageous or out of line, but from what ive been told, vodka dosing only covers one stage of the carbon dosing whereas this covers 8 )from what ive been told.

And yes, I was joking about bioballs.


These threads range in dosing of a single carbon source: vodka


So, i have copy and pasted a small amount of the article you posted and it supports everything I have said. IT is a carbon source to feed bacteria to then eat the trates. Unless im missing something very essential, i believe this item is worth a try.

 

[Dannyrb26]

some of the red sea stuff works others dont u bascilly have to buy the whole red sea gear to get everything to work right

 

[Jmck]

Thats the aim for the moment, just try their program with some common sense. So lets hope it works nicely.

 

[phastroh]

I stopped all the algae in my overflo but cutting the top of my 5Gal top into a triangle with the curve of course.

Nuttin, nada, silch.

Just saying it hasn't grown back at all. Woot Toot!!!!!

Now if I could only block the Chaeto light from shining on the water cascading down the black plastic in my sump and I would not see any.

I have been using Dr. Tims Waster Away and My Nitrates that were at 40 are now and have been for a month at 10PPM.

He also has other stuff I will order to help even further.

 

[martinlevy]

To try and explain. this stuff feeds existing bacteria and they multiply faster by adding alcohol, methanol or red sea nitrate remover. These bacteria deal with ammonia and then nitrite but will only then turn to feed on your nitrate if they are starved on oxygen, if they have oxygen they will not feed on nitrate as oxygen is easier food. The trouble is starving your whole system of oxygen so to force bacteria to eat nitrate means doing the same to your fish and corals and will kill everything. thats why we use a reactor. an enclosed chamber filled with substrate which is fed with alcohol, methanol (the ingredient in Red sea remover) or sulphur. you get a massive poulation boom but water is fed through at a trickle. therefore there is not enough oxyen in there so they turn on to eating nitrates instead. being in a small enclosed chamber there is less risk to your livestock in your tank. Turning your whole system into an oxygen depleted chamber could be lethal.

hope this helps

 

[Jmck]

Good explanation martin :) However you can also balance the oxeygen levels with the nitrate levels and get a good balance, too much of this nitrate remover or alcohol will cause issues, but the right amount can see excellent results without a chamber ;)
