Clowns?

[IceTurf]

I dont' really have no way of knowing if my hydrometer isn't workin, no there isn't anything fake in the tank, nothing made of metal that I know of and i checked everything before I put it in. Ok nvm about the clowns, last one died as of a few min ago, some coral around the bottom of the main colony i bought still has color, some has color because of coralline algea growth, but the stuff that hasn't been taken over by coralline algea near the base of the coral still has color so there is some hope yet. The other coral has plenty of color since I turned off my light, ok not plenty, but its still fairly green/red and for 2 full hours, its color hasnt gone down. I suppose its now saving the coral, any ideas? Theres no flow, I turned everything except for the heater off. They are acropora corals, one is a large colony, and the other one a fragement. Water looks almost cloudy white.
