My Tank Thread
Yeah but u cant always dose the bottle directions it can kill corals
I don't know that it can kill corals when dosed as directed. Sounds like an urban myth to me. Where did you hear that?
That said, I cannot give better advice for higher or lower doses without some sort of measurement of them by, say ICP-MS.
