help with blue green algae!
I hvae a 100g tank with 2x96w, 1 4XODNO 48" tube, yeast Co2. I noticed blue green algae grwoing on the substrate and leaves of my plants in the higher light areas of my tank. What is causing it? How can I get rid of it? My algae eaters wont touch this stuff (SAE, platies, mollies, rosy barb, otto, pleco). I dose KNo3 up to 15ppm. I heard of people using erythromycin? Has anyone tried it ? THanks. I appreciate any help!
