New Install -- FC at 8

Sure. Most VS pumps are really inefficient below 1000 rpm or so. In other words, they move very little water for the power consumed. At what rpm will your SWCG operate? Could you run at that level and then have the SWCG add continuously?
 
Dab,

While you need to run the pump fast enough to close the SWCG's flow switch, you should not need to go into any "Beast mode"

Tell us what speed you are running in Beast mode..??

Running faster will not produce any more chlorine.. I run at 1200 RPM and still make chlorine, more like Mouse mode... :mrgreen:

Thanks,

Jim R.

I didn't even think about it until just now. Beast mode is around 3500rpm. I ran it in that mode for the suction powered pool cleaner, which I replaced with the Dolphin. So, I don't need to run it that high. I'll lower the speed and monitor. Still working on the chemistry -- raising CYA and lowering PH a smidge.

Even at 8, I'm still pleased as I have had no manual intervention with the water, except testing and the pool is clean and clear. Truth be told, my son has been testing, so I am almost hands off. :) I did enter the numbers in pool math -- so...
 
Dab,

Running at max speed is just like having a single speed pump... ☹

I also run 24/7, but mostly at 1200 RPM... It costs me less than $20 bucks a month..

In my mind there is no reason to run the pump if you are not making chlorine..

But.. As always.. Your pool and your rules.. :mrgreen:

Thanks,

Jim R.

Losing 8 hours a day of 2700W should look nice on the electric bill. Find the lowest RPM the SWG activates, Raise it by 100 or so to give yourself some wiggle room due to a dirty filter or full skimmers and let it be. If the water is always moving the only stuff that settles to the bottom is the heavy stuff that probably would have sunk even with the high speed flow.
 
Sounds like a plan. Also just in case you aren’t aware, there is a growing movement of us that target being slightly above the higher # of ‘in range’ so if something was to happen and a loss of 4ppm was had, We would still be chugging along just fine.

monsoons, ridiculously hot and sunny afternoon, spur of the moment party....... heck the SWG could stop working for whatever reason and you’d allow yourself a whole extra day to realize it before there was an issue. Because let’s be honest..... most of us with SWGs aren’t exactly checking them daily.
 
I have just started my SWG this last weekend at 25% for my circupool edge 40 for a 23k pool and with CYA-70 I'm still at FC-8.5 as of last night. This is in TX heat. Pump is currently running 24/7 @ 1800 rpm. Lower RPM and I loose the spa spill over. As TP once sang- I won't back down.

Went out this morning to check pump settings. It had been on 800 rpm for most of the day, with it ramping up to 3500 for six hours. I changed that to 2500, which will spill over and should be enough to cycle through the water in the spa. I had kicked the SWG down to 60% and will monitor.
 
Even going down to 2500 from 3500 saves far more electricity than the proportional 1/3 of RPMs. Those last few clicks up are expensive.
