I have a 20gal long with an xp3 canister and spraybar. I angle the spraybar at the surface for agitation. Then in one end of the tank I have a koralia 550 angled up and at the opposite tank wall. Tank is spotless and circulation is even throughout. I have a gramma and two tank raised false percs in the tank. Just going to start adding corals in the near future. Have an esopps psk100 skimmer hanging on the back. So far so good.
May all of your fish be healthy ones!!:
