Just put in a new Intellichlor IC40 cell, and the pool company I had do the install (to get the full warranty) said it needs to be set at 100% during the summer (Friendswood, texas). I told her the last IC40 I had, I never had to set it anywhere near that high.
Does this sound right? What should proper setting be? My pool is pretty large, approx. 20' x 45' with a 9 ft. deep end.
