So we cleaned the filter. Yep, took it apart and recharged it with new DE powder. FC prior to the recharge was 22. Figured that wasn't too high for the kids to be in so in they went!!! Total of 5 people
swimming for about 2 hours.
I was showing my SIL how to do the FC testing and guess what my FC level was! FC = 26!!!! How did I gain 4ppm 3 hours later after 5 people swimming?! This is boggling my mind!
Obviously, at that FC I didn't add anymore bleach. Actually there was a storm coming, so we covered the pool to call it a night. May get one more reading after the sun goes down ...
