Eliminating wipe off brown algae in 20 gal long
I set up this tank in late January, and continue to have brown algae that is easy to wipe off. I expected it would be gone by now. I was doing weekly water changes (but am now doing one every 3 days). When I clean the water it is the color of light tea. Nitrates are ok (5 ppm), nitrites and ammonia are zero. Plastic plants; lights are on about 12 hrs/day and the tank is not in natural light. Usually when I change water I am also removing the decorations and cleaning them too.
Stock: 3 cories, 3 cherry barbs, 5 gold barbs, 1 dwarf neon rainbowfish.
