Also keep in mind that 2 inches of rain, which is usually more than we get at once, will only dilute a 60 inch average depth pool by 1/30th. Not enough to even notice.
A 6 inch monster of a storm will only dilute you 10%, and your FC should not have been that close to min under any circumstances anyway.
The key is circulation. For those running a schedule, it may be 16 hours before the pump kicks back on and 0 FC rain water may go funky on top.
Got it. I will target the higher end of the fc range starting tomorrow. I’m also currently running my pump 24/7 because of our heat pump (it’s dropping to the 50s at night but nearly 90 during the day).
