Can anyone comment on these? I have a 20x40 inground pool (33,000
gallons) and I keep hearing how great these are. One thing that isn't
great is spending so much on chlorine tabs and shock every year so I'm
very interested in putting one of these in for the spring.

I looked at a few brands briefly online, the Hayward Aqua Rite seems to
be the one I see mentioned the most, reliable manufacturer, etc.

From what i learned, it's good to get one of the newer self-cleaning
ones to avoid buildup on the plates.

Any comments and good sources as far as where to buy it from would be
great. I'd probably self-install, doesn't look too tricky.
