Hey everyone. I have bought an air pump and a sponge filter, and now I have a couple of questions for you to answer please
1. Do I need to do any special preparations before getting the filter working?
2. After looking into water change recommendations with a filter, I guees I now need an gravel vacuum too. I have a 3.5 gallon tank with one betta, and I'd like a small one that would not suck up water fast so I could change water with the betta in it, and that will also be easily maneuverable (if that's a word).
