Why does this stuff always come back on my glass? How do I stop it? It comes off easily but it's really annoying. Also, I stil have this brown algae growing on my filters and power heads!!!!
I just had similar problems and it ended up being high calcium it precipitating out and was everywhere and reappeared almost as fast as I took it off. Test parameters and see if that is it. I did a water change to help lower and cleared up quickly. Good luck!
