I've had a target of 8 for my FC for the last week or so and it has been dropping to 6 or so, yesterday it only dropped to 7 or 7.5 but was an overcast day. Today it was around 90 and pretty windy, also the first day the kids got in for a couple hours and when I checked it this evening it was down to 4. Is this normal for it to drop that much in a warmer, windy day? The pool calculator had me put 142 oz. in today, at that rate I'm going to have to have a bunch of bleach on hand!!!
Thanks for any input anyone may have.
