Contamination Via Used Equipment

[Delphinus]

Also .. coraline will grow as long as you have good Ca and Alk values. Ok, so it won't unless you have some to begin with, but any chunk of live rock, or shells or CC (or a PH ;) ) or anything that has it on it will seed your tank.

So don't toss out that PH. If nothing else use it to mix SW (or ... I'll take it off your hands if you really wanna throw it out? ;) )

cheers
