IME, snails aren't affected by PraziPro, so you don't need to remove them.
Ok thanks. Ill make sure I double check the label as well.
For a beginner youre definately making a good start, most people wouldve got a fluval 305 and done waterchanges every week but for your single oscar you are definately giving him the best water quality.
I try. Most important thing that I have found is that its imperative to do research before doing anything in a hobby that requires this amount of work. It is work, but a rewarding work. The next best thing is to be a sponge, soak up all the information about it as possible and learn from others experience while you acquire your own. This has worked for me so far, whether its fish, cars, airplanes or whatever I am into.
