So the last few weeks have been hell watching my tan decline as I try to find a solution to this problem. I'm not sure if these algae are Diatoms, Cyano, or Dinoflagellates as they differ from dark brown to dark red. My parameters go as follows.

pH- 8.4
Ammonia 0
Nitrite 0
Nitrate 5ppm
Phosphate- Unknown as I'm using a shitty API test kit. But I am running a GFO reactor.
Alk 7-8 DKH
Calc 440ppm
Tank is 6 months old
Always use RO/DI

This nuisance started popping up right after I deep cleaned my sump and added new macro. I also changed from 24 hr refugium lighting to reverse photo period as I'm now using chaetomorpha. If anyone could think of a cause and solution to this problem it could really save my tank.
