Hello fellow homo sapiens pool owners, and welcome to me!
I live in France and have a pool. Pools used to be subject to a luxury tax here, but that was relaxed in the last 10 years, so a lot of regular middle class folks are getting pools these days. We are not allowed to have big pools like you Americans, only little ones. We have to pay a big luxury tax for bigger pools. Well, we got that "hope & change" here 50 years ago.
I have been a "good boy" and did real all the stuff I am supposed to read before posting. But I still haven't found what I am looking for. We use Bromine a lot in France instead of Chlorine. But all I can find on your nice site is "Bromine: An alternative to chlorine, most commonly used in hot tubs. Bromine can not be effectively stabilized against sunlight, so is not normally used outdoors. Bromine is more stable than chlorine at high temperatures, so it is often used in hot tubs."
Well if that is all that TFP will be able to help me with Bromine then I am sad and sorry to find such a good site but have to look more for another one.
