I’m currently working on the plumbing for a 40 breeder. Using a 600gph overflow and plan on plumbing a manifold for 2 valves for an eventual carbon reactor and UV. Any suggestions for a controllable dc pump? Several pvc elbows and I’m also doing a 2 nozzle loc line return. I have a sicce 3.0 ac pump in my cart at 714 gph but have my doubts that it will be sufficient
