Green cyano outbreak

[ovicez2004]

Hello, all. I've been battling with green cyano for 2 months now. It bottoms out phosphate like crazy. I am forced to dose phosphate daily, in order to not hurt the corals. I manually remove it every other day, but not very successfully. I wonder if dosing phosphate heavely like I do is in fact helping cyano, not my corals. Any advice?

I’m in the same boat as you as it also bottomed out both my N03/P04. I started dosing neonitro and a diy trisodium phosphate 10 days ago. I do see a small bit of hair algae cropping up so hopefully it can outcompete the cyano.
