corals staying open at night
hey. I got gsp, a kenya tree, 3 different colonies of zoas and none of them are closing at night? At 2 am I can look at the tank and my corals are fully open. Is this normal? There are no lights on the tank at night. In the day I have a 250w guisemann w. 2 t5 actinics.
also.. I am starting to get a 'crystal ish' looking stuff in my tank. It started on a rock and now it is at the base of a frag of zoas. It looks like little crystals or fuzzies kinda. Any ideas of what this is? Doesn't concern me too much as there isn't much... But if it starts to spread that won't be good.
