I got rid of the outbreak with hydrogen peroxide. Switched tanks. Put in more plants. Params looking good. But STILL I sometimes see grain-sized bits attempting to grow...What causes this, does anyone know? I searched but couldn't find anything, but it's like there are little Cyanobacteria spores everywhere, just WAITING to grow~~~~arrrgggghhh!!!
Sorry, I don't have a pic right now, just removed a few little dots:(...
