Hi, I was wondering if concrete was fish safe. I know saltwater is corrosive but i dont know what effects it will have on concrete. I was thinking of making base rock from concrete would this work? or would the concrete kill the fish or are they procedures i should follow to make it safe or select brands?
Also say when you fish tank and have a fish that needs open space were do you keep all the live rock?
One more thing when people ray you need 1 pound per gallon do you count the water that has been displaced by sand and live rock?
thanks in advace
