Hello, I have a 7 x 3 meter 4 feet pool with a 1.5 hp pump with 2 jet nozzles. The water speed of the jet nozzles coming out near the surface of the pool is barely noticeable. I guess the 1.5 hp pump isn't strong enough to have that splash effect from the nozzles. What would you recommend I do if i wan that spa effect from the jet nozzles? Some people tell me to add an additional 1 hp pump? If I do, then how will it be connected from the main pump? Thanks
