It is 50 lbs of live rock , never had a problem in the last 3 years, the fish were added 3 months a part over 2 years ago. I don't understand after a big turbo snail died my water turned cloudy and I got this brown crap all over my rock and sand

I read that turbo snails don't live long in captivity cuz of the warmer water. It could of just died. I don't know but that's what I read

I heard that about margarita snails, not turbos. Turbos are from the gulf. Plenty warm there.
