I would like to hear what everyone's water change routine is. Currently, I do twice weekly 25% water changes on all my tanks. However, my monster fish produce so much waste and I can't stand looking at it. I was wondering if it would be okay to do a quick vacuum every other day if needed? When vaccuming, I would only be taking out 2 to 6 gallons depending on how dirty it is. I'm weary about this because I would essentially be "topping off" the tank. I don't want to end up with old tank syndrome. So I want to hear what everyone else does to maintain a clean and healthy tank.
