Hi, I'm about 12 months into my tank and have recently seen a Cyanobacteria outbreak occur. I'm fairly sure it is Cyano... I clean the back of the glass weekly but now there is a brown algae build up that when I wipe it off it appears like a brown gooey type substance. There is a small bit on...

I tested my PAR and Lux for the first time today with my Seneye Reef. I have a shallow tank and am running 6 x 80W T5's. I am only running them at 80% power. The results were: PAR: Bottom: 470 Middle: 600 Top: 815 (1 inch below water level) Lux: Botom: 17,000 Middle: 22,000 Top: 31,000 I...

Hi, I am running a lighting system with 6 80W T5's. I was using 4 BlueWhite, 2 Blue and 1 Pink but have recently changed to: - 1 BlueWhite - 4 Blue Actinic - 1 Pink. I am using the RedSea T5's: http://www.redseafish.com/hardware/t5-fluorescent-reef-lighting/ I think with this setup i...

Hi, I am having problems with Brown Seaweed and Green Hair Algae. In the Brown Seaweed picture you can also see some kind of half circle flat seaweed also. photo(6).jpg is not a great picture but you can see the green algae growing on the right hand side top platform. It has since started to...

Hi, I have my tank up and running for just over 2 months now. Today i spotted a small black crab about the size of an emerald crab and managed to get him out of the tank. Does anyone know what it is and if its safe to put back in my tank? I had a Peppermint Shrimp and Cleaner Shrimp die last...

I have my Nitrates down to zero and phosphates down to 0.04. I was delighted with myself but when I was at my LFS I was told that zero Nitrates is bad also because it causes other types of algae problems. He recommended Nitrates at about 1 as I have SPS and LPS and he said this will be a happy...

I'm trying to deal with some Aptasia in my new tank. I got the chemical stuff that you inject into the Aptasia but they always retreat into the rock before I can get the needle inside them. I was thinking I could just cover the hole they live in with reef safe glue. Does anyone know if this...

Hi, Has anyone on here used the Hanna Electronic test kits? Are they any good or are the good old visual ones more reliable? I see they do one for Phosphates, Nitrite, Calcium and Magnesium but i dont see any for Nitrates...

Hi, I have a Powder Blue Tang for about 10 days. It seemed to be doing well, not stressed and eating loads. Its a 110 Gallon tank with only 2 other Juvenile Clowns. Today i noticed a darkish strip starting to develop near the tail on one side. Anyone know what this might be?

Hi, I'm 2 and a half weeks into a tank cycle (which was speeded up a bit by using Microbacter7). I notice my PH is slightly high ranging from 7.46 to 8.55. Is this normal while cycling a tank? I tested my KH and Alkalinity for the first time today and they are both elevated too. KH = 12.4...

Forget about the fish... it's me who cant handle the lights! I just setup my ATI Sun Power 6 X 80W Dimmable and at 100% i nearly need sunglasses to sit in the same room as my tank. I can see the tank from way down my street let alone sitting beside it. Would it be possible to counter this...

I thought that the optimal Salinity for Corals was 1.026 but i got Red Sea Pro to make my own water and in the manual it says that for Soft/LPS Corals 1.023 and for SPS/Giant Clams it should be 1.025. On their website it just says 1.0255 for Corals. I plan on keeping more LPS than SPS so maybe...

So i have been cycling my new 110 Gallon tank for the last week and just turned on the lights for the first time today. My last tank was an 80L. I still need to do a bit of tidying up with the cables for the wave makers and lights. The system is 70" x 21" x 18". I have a Deltec Apf 600...

Hi, I was thinking of adding an Ozonizer to my tank as i hear they are good for dealing with Bacteria and Protozoa that can infect the fish. Does anyone else on here use one and if so do you think they are worth the effort and cash? Thanks!

Hi, I'm just a couple of days into cycling my new 400L (105 Gallon) tank. My main focus is on Corals so i want to keep a light enough bioload. Here is what i would like to put in the tank: - 2 x Common Clowns - 1 x Six Line Wrasse - 1 x Copperband Butterfly - 1 x Powder Blue Tang - 2 x...

Hi, I just got a new tank and am a bit confused when trying to figure out what the water volume is. When calculating do i include the display tank and sump? Also, i know how much water was actually put in the system after sand and LR was added so maybe this is the figure to use? The display...

I'm getting a custom built tank done and want to have no background colour. It's a shallow long tank 1.8m long. I plan on having the tank only a small distance from the wall behind it... Maybe 40-50mm. The wall behind the tank is painted just off White with a small hint of yellow. From other...

Hi, I am getting a custom build shallow tank with the following dimensions: Width 180cm x Height 45cm x Depth 53cm (71" x 18" x 21"). Does anyone think 45cm is too short for the height? Are their any obvious problems i will run into with this type of setup? I want to house all types...

Hi, I am looking at purchasing these gloves: 50 Arm Length Aquarium Gloves One Size | eBay They are made from Polyethylene but their is no mention of High Density Polyethylene. Does anyone know if normal polyethylene is safe to use? Thanks

Hi, I'm in the process of ordering a custom built 500L (130g) rimless tank with no lid. I'm a bit worried that humidity will be a problem and I will have to replace massive amounts of RO water every day. Does anyone else run a tank with no lid that can tell me how much water they lose to...
