Hi Janet,

Thanks for the suggestions. I had not thought about going the high CYA route, but it does make sense. There is usually someone there every week or every other week during the swimming season, so if I can come up with some simple instructions (such as add 1 bottle of bleach) I might be able to make it work. I'll have to store the bleach in a different location from the rest of my chemicals, otherwise people would be tempted to "self medicate" the pool, which was another problem I had to address.

The SWG is also a great idea -- perhaps the better one. I know I really like the one I have for my home pool, and the idea of having the campground pool regularly chlorinated when it is unattended seems to be a better solution than to have a high dose on a sporadic basis. It would also cut out problems with coordinating the maintenance of the pool among several people. I only have experience with IG SWGs -- I assume it would be the same for the AG? As I mentioned earlier, I replaced the original pump/filter with a standard (Hayward) sand filter and pump, so I would think that adding the smallest in-line SWG on the return would probably work. Am I overlooking anything? Thanks again for your help!
