I have a 40 to 50 year old plaster pool 18' x 36'
I am estimating my capacity at 24,000 gallons.
Using the hth 6-WAY test kit i get:
PH 6.8 (at most)
total Chlorine above 5
The pool has a green tint to it.
From the given levels that I read I believe I should only being trying to raise the PH and keep the TA in check.
If I add borax will I not be also raising the TA? Should I add the amount of borax in divided increments as opposed to all at once?
Also CH is 220. I added a calcium chloride product called Prestone Driveway Heat. I felt a little uneasy doing this but the manufacturer said it is around 92% - 94% calcium chloride.
Could the low hardness level be a cause for the pools cloudiness?
Thanks for your help
