I've successfully completed 2 SLAMs, brought my CYA to what I feel confident is 40, but I'm still losing FC at what I would consider a fairly rapid rate. My pool only gets full sun about 6-8 hrs a day (mid morning through 3 pm) so it is shaded in the heat of the day and we aren't even close to the heat of our summer. I am having to add a shade under 3 quarts of 10% daily. I have my wife, who is off on maternity leave, add 1 quart around lunch not aiming for a specific number, just ensuring I don't drop below the minimum. I'll add another around 4, and then another after dark to get the FC between 8 and 9 for the night. Any suggestions or thoughts? It's getting expensive and I won't have anyone home to put an insurance quart of chlorine in much longer.
