I have been fighting algae. Right now the pool looks pretty good. It is 10:30 at night and the chlorine level is at 13 the CYA is at 30.
I added 5 gallons of pool store chlorine late this afternoon that got it to 13. According to the charts and calculators I need to add another gallon to get the level to 15 and see how that holds overnight. Is this correct? It sounds like an awful lot of chlorine.
