are you using live rock in your tank and what other water movement do you have? ie. powerheads etc. substrate? give us an idea of your set up and the inhabitants
55G 48x13x20
Live rock 10lbs maybe 20
Live sand 20lbs I don't know what kind (I will get more, slowly)
x2 660 powerheads brand unk (more on the way)
Protien skimmer odyssea ps75 (cheap I know)
Canister filter Odyssea CFS4 (again CHEAP)
Livestock
Open brain (red)was bleaching but color is coming back
Bubble coral
Northen red Anemone (not looking good since the move)
False perc
x3 Blue/Green Chromis
Some sort of clam (hitchhicker)
Plus another Anemone hichhicker, it's clear and about 1/8th inch across. I don't think it's a aiptasia because the tentacles are short, the aiptasia's are long right? I'll keep a close eye on it.
here are some pics
