I have a 20X40 free from with deep end 3 1/2- 8 1/2 ft. Also 8ft. diameter spa. I am using 2" pipes through out. Have 6 returns in the pool. the spa has a spill over and 6 power jets. It has 2" flex pipeing in it. I have 2 skimmers, an auto water leveler, and 4 deck jets. I dropped the waterfall I was going to have. My equiptment pad is approx. 40 ft. from the majority of my pool. I had thought I could get away with just the intelliflo, but my PB says that will not be enough to run all of that plus give me good action in the spa. He has never worked with an intelliflo before but says I need a seperate 2 1/2 horsepower pump to work the spa jets alone. He said I just have too much going on in my pool for one pump. Any thoughts on that? Thanks so much.
