Tredge, I can't go agaist Ben (not that it's illegal, just that he knows sooo much more than I). However, with an auto chlorinator, I suggest turning it on manually when people are using the pool and letting it run for 1/2 hour after they finnish swimming - this puts cl in the water as the 'bad' stuff is going in (having everyone rinse off before entering the pool will lessen the cl demand). I usually recommend a 'split' run time to allow the chlorinator to run while the pool is in use and a cycle at night to do as Ben says and let the chlorine really do it's job when there is no interference from bathers or sun. Hope this makes sense - Waste
