For the past few weeks after doing my weekly water changes my water will turn yellowish within a couple of days and progressivly get worse. I have a piece of driftwood that I boiled and placed in a year ago but the water situation seems to get worse as time goes by. Do I need to do a total tank clean? Could this be an algea bloom even though I do not provide a lot of light? I'm really lost to what is happening. It's just real dingy looking, it doesn't really seem to be algae.
