I get zero Nitrates in my tank unless I dose it and I don't use anything for Nitrate control. I test every week with my H2Ocean and have got my LFS to test it twice on their kits to confirm at different times. They have never seen it before either so their is something strange going on in my...

Thanks. I might try stopping the Nitrates as well. If I don't dose Nitrates my tank goes to zero Nitrates all the time though for some reason no matter how much food I put in. I was told by everyone working in my LFS that having Nitrates at zero will cause an imbalance and it will cause other...

My sand sifting Goby started moving all the sand in the tank around his burrow about a month ago which might have triggered it. Will it sort itself out or will I have to do something for it?

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...

Hmmm, my tank is only 17" high and the lights are fairly low over the water. Maybe i'll have to reduce the intensity dow to 60-70%. And there was me thinking more light was always better! It probably explains my green hair algae problem as well. I have Nitrates at 0 and Phosphates at 0.06...

I have a mix of both LPS and SPS. I have the LPS at the bottom of the tank. Everything seems to be doing well except for my Montipora Capricornis which has small bleaching going on the last week. I had put my lights up to 100% a week before that so im hoping that is the cause. I put 2 Blue...

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...

Thanks. I could try replacing the pink for one of the whites i took out. I heard that the pink helps bring out the red Coral colors though?

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...

I like the look of the brown stuff myself but im just worried its going to start taking over the tank. I have moved the large top rock covered with Algae into the sump (with no light) so hopefully given a week or so it will have died off. Maybe their are Phosphates leaching out of this rock...

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...

Thanks. Just googled it and found this picture of a Gorilla Crab which seems to look like what i have. Luckily i saw him poking out of a small rock that i could easily remove from my tank. Cant imagine the hassle of trying to catch one of these!

They seem to be pointed

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...

Just watched a video about the Aptasia X online. I think my problem is that my Aptasia are very small at the moment. I can't get anywhere near them before the retreat into the rock

I have the Aptasia X. Unfortunately in my failed attempts to kill one the first time I saw it release all it's babies so I'm worried when they all start turning up. I also put in a Peppermint Shrimp but that just hid under a rock for a week until I came down one morning to see my 2 cleaner...

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...

Thanks for the replies. I might try the Alkalinity one, I always find doing that test a pain.

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...
