I work 11 hour days, 6 days a week. We are about to get the water to level in our pool. Should I test the water before I leave at 5 a.m. and add chemist then? I cant be home til about 6 p.m. to do anything else. And the pump should be running during all this for a few days at least right? Should I adjust chemist again if I retest when I get home? All of this is slightly confusing, especially due to our working hours. Any advice would be greatly appreciated!
