My pool got very cloudy this past Sunday. My FC also tested pretty low at the time (.5 or lower), so because of the combination of the two issues, I determined shocking the pool was in order. My CYA had also slipped to 55.
I did have some algae after day one of shocking that sank to the bottom. I got that up with the vac. I see no signs of algae anymore, just continually cloudy water.
The T/A was on the rise this morning and at its top, was at 140. I noticed the pH was on the rise as well, at 7.8.
I added the recommended amount of MA and several hours later, I had the results posted below.
Basically, the pH is back where I want it but my T/A target (SWG pool) is between 60-90 and is therefore still to high.
Thus, my current readings on my second day of shocking (not able to hold FC overnight yet) are:
FC = 24 (recommended number for SWG shocking)
CC = 0
pH = 7.5 (was 8.2 this morning before adding 19 oz or MA [amount according to pool calculator])
T/A = 130 (was 140 this morning before adding 19 oz of MA [amount according to pool calculator])
CH = 90
CYA = 80 (during 1st day of shock, I also raised this number from 55).
My questions, which I could not find an answer for in a search of the forums is:
Should I not worry about T/A until getting the pool clear and can higher T/A make the pool cloudy? Also, is it okay to try and attack both problems at the same time (lowering T/A and keeping the FC at 24 until it stabilizes overnight)?
Further, if I should leave T/A alone for now, what else could be causing the continual cloudiness? Is it simply a matter of time?
