I have a similar cyano bacteria problem in my 40 gallon reef tank. I do water checks regularly and everything checks out, with only trace amounts of phosphates. I have a bakpak refugium with the protein skimmer, two korali 1 powerheads and a korali 3. my cleaner crew consists of astreas, conchs, turbos, hermit crabs, serpent stars, necarrius
and another breed of snail i cant remember. STILL, i have cyano outbreaks daily. it seems to fade at night but blooms during the day.
1. Has my bulb (36inch 96watt powercompact) deteriorated in such a way where the spectrum inhibits the growth.
2. When refilling evaporated water I use water from the tap (softened)
What to do!?
