Alright. It appears from a quick look at some old photos that my acros had better growth when the po4 was 0.10-0.20. But I wasn’t doing anything special to achieve that range.I’m also at 0.35 phosphate, all my acros are happy and healthy and also zero problem. I have no algae even without flucozonale. However, with my PO4 around 0.35 I often wonder if my corals would grow faster if it was lower, let’s say around 0.15
@Charlie’s Frags do you ever feel your growth would be better with lower po4?
