Does anyone know what this stuff is attached to my live plants, decor, gravel, tank walls, and heater? It looks terrible and despite wiping it off it will not go away. I dose with a carbon solution for my plants but haven't installed a co2 system. I can't seem to find one locally so will have to order one online. Is this something growing? Will co2 clear it up?
