I am new to the forum. Thanks for all great advice I have taken from the Pool School so far.
I am maintaining FC by using bleach. No other chemicals have been added to the pool water since spring opening apart from pH adjustment w/ acid.
Last week temperatures have picked up (88Â°F), and I had cloudy water.
I added HCl until pH 7.6. Water was still cloudy , so I added 1gal HCl to lower TA (don't know where to get aeration device).
Now the water is sparkling, BUT:
CH 550ppm (up from 330ppm, I have no idea where this comes from!)
CYA is >100
Tap water is
CH<50ppm (not a significant source of Ca to my pool.)
Now my pool water is too acidic to swim, and I need to add Chlorine quick, or else... green swamp.
If I add soda ash, I will increase Carbonates, water will get cloudy again. I was considering Borax to raise pH. Does it make sense just to increase pH with Borax, or will I have to add the whole 50ppm Borax?!? Not sure if I want to do that since I live in a rental. (Now pool guy bc/ I don't want them to dump more chemicals in for no reason.)
Balancing water does not make much sense bc/ high CH will always cause my pool water to get cloudy. Still I need to get Chlorine into the pool quick - which one to use that is not destroyed by acid?
Is CH and TA reading (FSA-DPD test kit) influenced by water temperature?!? Do I get falsely high readings?
Confused, and grateful to anyone who shares their wisdom.
