I did the pool chart entry form and will complete the results this afternoon when i get home. I am already at work, it is too dark when I leave in the morning to test. I asked my husband to test before he leaves this morning if he has time to do it I will record them. I will put in the readings from yesterday morning for now. i did dump 3 gallons last night as advised.
