Wow - there's a wealth of information here. Thanks for putting this site up - it answered most of my questions, but I still have a couple.
I have an 11,000 gal in ground pool with an AutoPilot Pool Pilot SoftTouch SWG with an SC-36 cell. The pool is gunite and about 4 years old.
I know the chemistry is completely whacked - I'm going to work on getting the water balanced and try to train my family to do some basic tests and maintenance while I'm not at home so it doesn't go out of range again. The reason I got into this mess was that I didn't know about the importance of stabilizer (perhaps I forgot, but I don't recall being briefed on it by the pool builder). After 4 years of tropical storms, backwashing the filter and kids, my CYA reading is non-existent (I do my own testing). Fortunately, I know what I need to do now, to get the chemistry corrected (thanks to this site).
As I said, I have an SC-36 cell. I had to replace it once (after 2 years) and I'm going to have to replace it again - cleaning it (I had significant white buildup on the plates) repeatedly has rendered the plates almost wafer-thin. When I do replace it (after balancing the chemistry), can I replace it with an SC-48, or is that overkill? Will the SoftTouch unit support an SC-48 and are there any jumper settings that I have to change when I change the cell?
Also, I've read a lot about the Pool Pilot Digital units and they sound like the cat's pajamas. Is it possible to simply swap the SoftTouch unit with a Digital unit, or are there changes that have to be made in the wiring, setup, etc.?
Again - thanks for this site!
