I have a 75 gallon Bow front, with about 50 lbs of fiji NOT sure if it is alive. Here is the deal had some electric problems that killed all the bristle worms so I am assuming it might have damaged the rocks, had high nitrates when i moved and set up the tank the rocks were always shipped in water that I kept to cut down on water cycling and change. I have a whisper filter with dual bio wheel think it is a 400 series or the like, under gravle filter with three maxi jet 1200 air jets one is on the cyclone protien skimmer and two coralife T5's I know pretty basic right? I was told this is all I needed to maintain this tank but all the fish keep dying undulated trigger, yellow tang was nothing but a skeleton and some flesh, a dominoe damsel, sargent major which i think might also be the problem and a 21 inch snowflake eel the only one in the tank is the sargent major damsel... all my levels seem to be correct , the guy at the pet store says if the rock is dead it cannot come back that even IF i add live rock it will only cover the fiji i already have and that it is considered just base rock. Is this true, Can I bring the live rock back it has NEVER been bleached nor left out to dry out. Also how do you tell if in fact it is dead?
