I’ve been in the hobby for about two years now and am experiencing my first battle with cyanobacteria, or what I think is cyano.. When the tank’s lights are completely off, the algae seems to bloom and throughout the course of the day the algae seems to fade when exposed to my 6 ATI bulb T-5 fixture (new bulbs). First picture is at the beginning of the day when lights first turn on; second picture is at the end of the day, before lights out. I was always told that cyanobacteria would do the opposite by shrinking in the dark and growing in the light.
This battle has been going on for about 6 months now. The algae isn’t getting worse, but definitely not getting better. I’ve done multiple 3-day “lights-out” attempts, with blankets over the glass with refugium light off. Weekly 10-20 gallon water changes using RODI water, TDS meter measuring 0. I ran GFO for 3 months. In my sump, I have tried activated carbon and multiple bags of Chemi-Clean / Chemi-Pure elite.
Circulation in the tank seems fine, and at times too much. 2 MP-40s and 1 MP-10. My NWB150 Skimmer and refugium seem to be doing their job.. And with Nitrates, Nitrites & Phosphates all undetectable, I’m starting to run out of ideas..
Temp: 76-79, SG: 1.026, PH: Ammonia, Nitrate, Nitrite: undetectable.
