20 gal high power head placement

Hey guys. I fully understand it depends on what your aquascaping looks like, but I was just trying to get a poll of how you position your power heads on a 20 gallon high aquarium. I have two Korilla powerheads on the back wall facing the front of the tank on about a 45 degree angle. I think that I have a bit of a dead zone in the back of the tank. One of the powerheads is a 245 gph the other is a 425 gph. Can you send pics. Do you find that low flow causes algae or a safe haven for a shrimp or other invert. Let me know. Thanks.
