    Should I get the 40K gallon cell for a 24K gallon pool?

    Should I get the 40,000 gallon cell for a 24,000 gallon pool?

    I think I read to get the biggest cell you can afford. Is this the way to go?

    Thanks!

    Our general recommendation is to go 1.5-3 times your pool size, so even a 60K wouldn't hurt.

The SLAM process is not finished until: 1. CC < 0.5 ppm, 2. An OCLT < 1.0 ppm and, 3. The water is crystal clear.

    I would. But I'd wait for more input.
    I'm running a 60,000 gallon CompuPool on a 44,000 gallon pool, and it seems to be just right, very happy with it. The 60k is only $110 more.

    That would be a good size. You don't want to go much bigger than 3x the pool size because the granularity of the settings get too great.

    Re: Should I get the 40K gallon cell for a 24K gallon pool?

    I'm running a Jandy 1400 40k gal cell on our 33k gal pool. Pump runs 24/7 and 35-40% duty cycle on the cell keeps me between 5 and 6ppm FC. 40% has kept up with 93 degree water temps and ambient air temps in the high 90s or low 100s with 10 hrs of direct sunlight per day and 70ppm CYA. I expect to be able to dial it back significantly once the air and water temps drop this fall.

    Based on only my experience so far with this unit. I think you could get away with a SWG sized a moderate amount above your pool capacity IF you run the pump most of the time. In my case I think my unit might be able to keep up with a 12hr pump duty cycle, but any less than that and the cell wouldn't be enough.

    I know I'm just a newb here, but I wanted to give back since lurking in this forum along with the TF100 has given me the tools to whip the pool into shape and keep it there.

    I have a CircuPool RJ45 (45k gallon) on a 24,000 gallon pool. Running for 8 hours per day on 30% has kept me at 5.5 FC.
