How well do sponge filters work? I am on a budget and am in need of a filter for two 10 gallon tanks. I have looked them up and they are the cheapest. Also interested in them because of a more calm flow for my betta. Just wondering if they work well enough. One tank will just be a hospital/fry tank and the other has 5 emerald rasboras and a betta.
