i used to have a fowlr, well i had a big out break of ich and i used copper to get rid of it. now i changed the water, cleaned the hell out of all the parts (ps,pump,new sump, etc...) the live rock i left out of water for about a week, i got angry at my tank. but i changed the sand only thing i have from the old tank is the dead rock. will this ruin any chances of me setting up a reef???
also when you buy lr from a classified ad is it posible to know if copper has ever been used?
can i use one of the pads that are meant to absorb heavy metals, and will it help with any copper?
