Quick ? everyone,
I have a 20gal AIO and the surface skim/overflow to the back chamber has slats at the surface and the bottom. That chambers opening to the next(bio media) is at the bottom also. Would it be a good idea to block the slats/comb to make the water enter from the top, thus surface skim & mech filfer?
