You should have seen it a month ago. Really bad cyano! The corals looked bad for a month previous to the outbreak. I tried everything. The answer for me for the time being has been prodibio bio clean. It works a lot like vodka dosing and bacteria dosing.
not as expensive as people thing. IMHO it's safer than vodka too. I think my real root problem is that I started the tank with almost entirely "dry rock". It is making it take forever to really establish. I'd like to get some good Figi rock for the some time soon. I think that will help a lot.
