I've been constantly cleaning the aquarium and battling this thing for over a month now, using diy coral snow, plus corals snow+bacteria for the last 3 days, while also dosing phosphates as they're tanked, and don't seem to be able to get rid of these. I clean everything. I vacuum, blow them off the rocks and corals w a baster but can't seem to get rid of whatever this is.
I can't tell if it's cyano or dinos, and I want them out, it's really stressing me out I'm really worried about my corals and fish.
I clean and the within the next hours the glass and the substrate and rocks are all covered again. I'm really frustrated

I’m sorry to hear. But it would help if we knew your parameters, and how old the tank was.

Based on your description, speed at multiplying and pics, I’d say golden Dino's.
Do they disappear mostly when lights out only to reappear when lights on?

Around 4 or 5 months old, 300l w the sump, dkh 8.5
Ph 8.2
No3 10-15ppm
Po4 < 0.01, trying to raise to at least 0.03ppm
Nh4 0
No2 0
Salinity 35ppt

Also have a refugium running in an inverse light cycle, skimmer 24/7.

I'm really frustrated and worried about my fish, they all look good, but still it is worrying me

Looks like dino. A decent sized UV sterilizer will help tremendously.

I wouldn't say they dissappear but it seems to be less of an issue w lights off, I only use the blue and uv purple. What should I do?
