Im having trouble with the FC. Over night test it will dip to 1 or even below. During the day it hovers around 2. But I can't get it any higher even when I have the SWG set on 80%. The pool water is blue but perhaps has a very slight haze especially during the morning before the pump comes on. But not enough to be called cloudy or change the color of the water.
I've cleaned the filter, cleaned the salt cell, added CYA (because that was a little low), and for the past two days the SWG has been on 80%. No dice...can't get the FC above 2.0.
CC is zero and phosphates are also zero. Salt is 3400. There is no evidence of algae growth. So im thinking either something is wrong with the cell or something in the pool has to be eating up the FC. pH is in range but alkalinity is a bit low but dont think that has anything to do with this.
Should I shock the pool? Have the SWG checked? Increase the pump run time and give the cell a few more days?
Thanks for any help.
