Compupool

I agree with BTG that you should oversize the unit. I use the SC-48 for my ~22,000 gallon pool. I however work on the philosophy that less over a longer period is better. I run my pump on a split shift with 4 hours during the peak of the day to combat the UV rays destroying my chlorine molecules and 4 hours during the middle of the night for a total of 8 hrs every 24 hours. I find this is the perfect scenario for my pool. Of course everyone's situation is different. One thing that I have noticed is that I have had absolutely no buildup on my cell. My calcium levels are next to nothing, so I assume that is why, but the Autopilot (and probably most units out there) reverse the polarity going the cell every so often (user setting) to combat any buildup.

A colleague at work also has a SWCG (brand escapes me at the moment) and loves it. Only issue he has is dealing with the calcium buildup on the cell at the end of the season. He simply soaks his cell in a bath of Muratic Acid to clean it.
