I can't get my free chlorine up....Its a 17000 gallon pool. The CYA was low, arounf 25, so I'm bringing that up, but last night I put in 2 1/2 pounds of shock, kept the pump and SWG on all night, tested this morning and the FC was about .5
The TC is still very high...
The water is very clear. Could there possibly be some type of algea eating the chlorine that it not visible?????
