Hmm, Is there anything else than Phos? I had a bad outbreak, right after I added more light??!!? 4 t5's over 2. Did a blackout, it disapeared, week later, coming back. Just got Salfert Phos kit, no reading??? Ir, is it not Cyano? Looks red and slimy like. Covering my sand. Not like it was, speckeled now, not a thick carpet like before
