I have a 210g tank that im currently having a cyano problem in. Its a baby tank ( age wise), less than 3- months old. Ive old had 10 baby chromis in their, so the bioload isnt overloaded. I've been feeding the fish flake foods only. I tested my phosphate 2 weeks ago and it was 0.15 ppm and this week it was 0.07, both tested were taken with a hanna checker. I run a BRS dual GFO reactor, a phosban 150 with gfo and i run bio pellets as well. I have a reef octopus SRO 5000 skimmer rated at double my tank size as well. All my water is RODI (All the filters and DI resin were changed about a month ago).
Im honestly not 100% positive its cyano since ive never really had it before. It appears to me like diatom algae but its more like red fibers than slime or algae. Heres a picture i took. its a little distorted from the angle of the glass.
Any tips will help, thanks!
