-Addict, I had exactly the same issue on my 90 reef with 330W PC
, running for around 18 months - very little corraline on glass or rocks. Recently I became suspicious of phosphate levels (none tested but I had a hair algae and cyano
outbreak). I put some Rowaphos in a home-made reactor in the sump. Wow! what a difference! Hair algae and cyano
vanished over a 3 week period and the corraline has gone INSANE!
I've heard that high phosphates inhibit corraline but had no idea the scale of the thing!!!
