I have some of this stuff fading on and off in my tank. I always thought it was a type of Dino. Bubbles in the stuff and everything. It’s slime like and goes away with the lights off.
Any product anyone has had luck with? I have had it before and it just went away but ever since I transferred my tanks into a Rubbermaid it just comes and goes when it pleases. Seems to come when nutrients go up is the only thing I noticed.
