I will tell you what worked for me.....
I had GHA. Bad. So I pulled each rock and scrubbed it then put them back after I rinsed with rodi water. Bad mistake. got a cyano outbreak from all the dying GHA. was at my wits end. nothing worked. Until I did this:
1. bought a spectra pure RODI unit - got tired of relying on LFS water that was "RODI". But it has a PO4 of .75 yes I tested it.
2. Started using BRS high capacity GFO.
3. took some of the red spectrum out of my LED current IC lights.
within 1 week zero cyano, and within 2 weeks zero GHA. its been that way now for quite some time. its actually been LESS maintenance than before.
