Before looking at filters for a 20 gallon why don't you consider upgrading a bit more to a 29 or 40 (or as large as you can go) gallon tank? That way the upgrade lasts much longer. Right now your turtle's in the middle of his first year growth spurt and that 20 gallon tank won't last through the end of it. He'll be cramped for space soon and you'll be looking for another upgrade before you know it.
