I'm currently cycling my 10 gallon tank, it needs about another week and a half to go (or so). I want to be well prepared for a new fishy, so I need a bit of advice on water changes. How do I get everything clean without getting rid of good bacteria? I'm familiar with using a gravel vacuum, but other than that, what should I do or not do? Should I even rinse the decor or tank itself at all?
Especially after the tank is cycled, I've read that I should do a "major water change." What exactly does that entail?
