hi there, for your case, i recommend a diffuser, like a glass ceramic diffuser. Those that look like a swirling glass thingy. It can be sold at many LFS, price range from a little under 10 to about 15. A good one costs 30+. Anyway another alternative is to use a flipper, the ones that come with nutrafin co2 set. Btw, what is the dimension of your tank? above 2 ft, internal filter would not be advisable. 2 ft is ok though
