My guys are doing the plumbing today and I'm telling them 2.5" from each of my 2 skimmers to the pad and 2.5" on the 6 returns. Also 2.5" to each of the 2 loops in the spa. Each loop contains 6 jets. The higher loop will run off my inteliflow and switch like a normal spa. The second loop wil run when I hit high flow in my intelli touch. Then a second pump with blower will come on and power the second loop. This will not go through the heater. It's just for additional flow and power. The spa is 10x10. I was thinking that 2.5" will be sufficient for this application due to the separate runs. Pad is around less than 60 feet away. Thanks in advance Steve.
Also separate suction for the two pumps in the spa.
