I just changed a new pump to drive my chiller but the next day I saw my damsel fish die and a day after another fish die... what could be wrong with the pump? I checked water para and all within ranges ....
I have brittle stars growing fast in my tank. when turn off the light, all the brittle stars will come out and almost cover my LR. is that good or bad to coral tank?
I have two birdnests, initially both put at highest place and directly under led light. after sometime, one is blooming and the other is fating . What could be the reason ?
