FC has been low and it was suggested I have algae and should SLAM. I used the Pool Math calculator and it said to raise my FC from 0.5 to 24 I need to add a little over 6 gallons of 10% liquid chlorine.
Yesterday I added 4 gallons because I didn't want to overshoot. Tested an hour later and FC went from 0.5 to 1.0.
Added another 4 gallons. Tested an hour later. FC 1.5
Added another 2 gallons (that is all I had left thinking I only needed 6!). Tested FC 1.0
We did turn on the SWG because the manual said FC 1-3 was okay. So ran it all night.
Pool water is crystal clear the whole time. Pool water is still clear this morning and this is the first morning it doesn't even have anything on the bottom that needs to be vacuumed.
This morning results:
FC 0.5
CC 0.5
TA 80
CYA 60
pH 7.0? Not sure, the color is orange. Doesn't match anything. So either lower than 6.8 or between 6.8-7.2.
Why is my FC so low after adding so much chlorine? The pool math calculator recommended to add 6 gallons and I added 10 gallons yesterday and barely raised the FC level!
