Hi everyone first let me say I am sorry I have not been around much I have not had internet at home until this weekend and I have really missed all you guys. Now on to my problem. LOL in my 55 gallon I have had an out break of bba it is growing on my swords, on the HOB filters were the water flows back in the tank as well as the tube that takes the water to the filters from the tank, and on my large piece of driftwood. Yesterday I trimmed off the leaves that had the bba, scrubbed the filters and removed the piece of driftwood as well as doing a 50% water change. What else can I do to try to get rid of this stuff and what could be the cause of it? I can only do my water changes twice a month right now because thats when my husband or mom can help me I can't do it by myself due to my back injury but the nitrites, nitrates, and ammonia have all been staying at the correct levels and fish are all doing well its just this algea that is causeing me trouble. Any help or ideas will be appreciated.
