85 GPM costs too much in power.
Slow it down as much as possible while still providing the necessary flow for the purpose.

You can do the following. Lower the rpm while the heater and SWCG are on and see where the flow limit is for the heater and the SWCG to not work because of flow. Now raise the rpm say 200 more and it should be perfect for the pool and $$$ savings. The heater and the SWCG don't care how fast the water runs and neither does the pool as long as there's enough flow .....
When the pump is running (and SWG generating, and associated electricals), power consumption is just approximately 1900 watts.
I remember a couple of years ago I experiemented with lowering the RPM to see the power savings while making sure the SWG and heater would kick on, and it wasn't much lower than the current 3000rpm (85GPM).
While I certainly don't want to spend more than necessary, 1900 watts for 12 hours/day costs me less than $5/day. For the 120 days/year I have the pool running, that's $600. I don't know what the delta would be if I lowered it to 200 rpm above the minimum for the SWG/heater, but I suspect the rpm delta would translate in a pretty small dollar delta -- at the risk of a less clean pool (or worse, the SWG and/or heater not working reliably).
