We just had our pool installed a couple of months ago and I have been using the PoolMath calculator to maintain my pool. It has been awesome once I got all of the levels balanced and I have had basically zero chemistry type maintenance the 2 months of hot weather we got to use it. My question is now is what do I do this winter? We plan on keeping the pool running all winter and not "shutting it down". We will not be swimming in it because we have no heater but I don't really want the hassle of starting it back up in the spring. It is vinyl liner pool located in South Carolina. The water temperature is now about 72 degrees. Typically we can swim again in April. Obviously since it has cooled off some, my free chlorine levels are pretty high 12.5. I never got FC exactly dialed in as they were always in the 9-10 range in summer. I kept making small adjustments to the SWG percentage and the pump run time. I was down to 8 hours a day of pump time and my swg set at about 45% when I got the 9-10 FC readings.
So with the 12.5 FC that I had today, should I dial the SWG back to about 25% and the pump down to about 6 hours a day? That is what I did before posting.
How is the best way to run the pool all winter and not have any problems in the spring? Will high FC damage the pool in any way?
Thanks for any help you can provide.
