I've thought that may be the solution but I'm concerned I would just always be running it on high anyways (at least in the summer when I use the mist coolers which can last nearly 6 months in Houston). There's a few different scenarios for myself where the requirements for flow would be different
1. Most common: Pump running in pool mode with with spa spillover, misters in place, some flow returning to spa to circulate.
2. Pump running in pool mode with spa spillover, no misters, some flow returning to spa to circulate
3. Pump running in spa mode, all water to spa
4. In either of the first two cases my pool cleaner could be running as well. I'm not sure this matters as it runs off the booster pump.
I'm kind of stuck between having a pump that's over sized for my piping (1.5 inch) which seems to be causing a very turbulent environment in my pump strainer basket and not to mention the cost, or the other scenario of purchasing a smaller pump and possibly running in to not having enough head to properly operate the misters (which I love because it's so Dang hot here anyways lol)
