How do I controll brown algae in my aquarium?
I have a 40 gal tropical fresh water aquarium, and it keeps getting brown algae on the rocks and on the glass. I run the lights about 12 hrs a day, keep the water at 76 degrees, and have no live plants. I keep about 12 quarter sized angel fish . I do partial water changes and clean the rocks and glass weekly. I would like to keep from adding extra chemicals. any suggestions please?
Your problem is light. Brown algae grows when there is light that's either low intensity, or lower on the color spectrum.
If you have no live plants, reduce the hours of lighting the tank receives per day.
Keep in mind, brown algae is harmless to fish. Some fish even eat the stuff. There is no need to add chemicals to get rid of it as it's really not dangerous to the fish. Reducing the amount of lighting your tank receives will reduce the amount of brown algae that grows.
