Cell size, and a couple other newb questions

[standfas]

I just completed a 21600 gal. pool. PB put in an IC20. I was not satisfied with the performance and am moving up to the larger cell. I spoke to a Pentair technician and was told that they both use the same power pack. I'm able to move up to the larger cell for an additional $50.

There some good photos on this website:

I just installed IntelliChlor SWCG yesterday, using the IC40 cell for my IG ~18K-20K pool. I'll finally know the gallon size when I refill it this time.

Price wise there isn't all that much difference between the IC20 & IC40 cells, so I went with the larger cell. I figured I could run it at a lower power setting than the IC20. It may or may not help with cell life also, running at the lower power setting.

I haven't run it yet, as I'm still working on remodeling and upgrading the pool equipment. I'm about 85-90% done with the remodeling, and hope to be filling the pool before this next weekend.
