I am kind of a clean freak and like to vacuum the tank/partial change at least 1 every 2 weeks. I also like to take a cloth and clean the inside glass since it is a little slimy. I also take out the power filter and heater and wash them real good with warm water (no soap of course). I also rinse out the blue charcoal and bio filte . Now that I am learning more about beneficial bacteria, I wonder if am I doing more harm than good?? ??? Will this make the tank water stressfull to the fish. My goldfish seem to be happy afterwards?? ???
