I have a 17k gallon salt water pool. Currently has a 2 speed pump, that I have running on high for 12 hours every day. Some pool guy said that was ok, but I did some reading and I might be able to run it for less time. Any help?
Take a photo of the Salt Cell or post the model number. Most likely a T-15 cell. I installed my Salt Water Chlorine Generator yesterday (after 13 years).
Your pump running time would be as long as you need to generate the chlorine you need. Any time after that is for aesthetics such as skimming, etc.
I doubt high speed will ever be needed.
