Not trying to argue with Sean or Mark. But I would appreciate it if you explain how my Aquarite unit tell me the water temp if it doesn't have a temp sensor? And it appears to be quite accurate when compared with the 2 pool thermometers I have in the pool and with my Goldline solar controller.

As for increasing the salt, if it works then that is great. But if the unit does have a temp sensor and shuts off at 55 or 60, then if the water temp drops below that, adding more salt won't do anything, will it?
