So since I upgraded to my 20 gallon, I've been running both my new and old filters together. The new one is a Top Fin, I believe a SilentStream, meant for a 20 gallon tank. The old one is a Tetra Whisper 2-10i. I think it just hit 3 months that they've been running together. I've been having some algae issues lately and I just looked at the Tetra filter pad and the little mesh grid that's included. The grid looks nasty, full of algae in the little mesh stuff, and the filter pad is falling apart and coming off the plastic that holds it up. I removed them, also because when I moved it slightly, a bunch of small particles went out into my tank in a cloud lol So my question is, at this point, should I be fine switching completely to the filter meant for the 20 gallon tank? My tank is cycled and I only have a small bioload at the moment--just a small Betta girl and 2 Horned Nerite snails. I also plopped in a dose of Stability to be on the safe side.
