Looking at possibly putting together either a 1 1/2 incher or a 2 1/2 incher. Would have everything but the pump. This will be a long arm system, as I don't dive.
What are the average GPM/GPH rates for pumps for those sizes, bearing in mind this will be a suction nozzle rather than a jet system, but might go jet later. Was kind of figuring the HF 1 inch clear water might be alright for the 1 1/2 incher.
