I setup my pool two days ago. I am off well water, with an industrial water treatment system including iron remover. Initial PH was 6.8, CL <2. I added CYA based on pool calculator to bring it to 30 ppm. I added bleach when I added they CYA (I overshot) and ended up putting in 12oz , and then 15 oz.
Testing yesterday evening showed:
FC - 5
PH - 6.8
TA - 160
This morning I added (per pool calculator)
44oz borax (called for 56 but I didnt want to overshoot)
I also turned on the filter (to aerate since my TA was high and remove come FC) and removed the cover (to help the sun remove some FC).
6 hours later I tested:
FC - 5
PH - 6.8
TA - 190
I added per pool calculator: 44 oz borax(the rest of what I had - calculator called for 66). and continued to leave the pool uncovered and filter on.
I am concerned:
1. Do I need to be testing for borates since I am adding borax to lower PH? I didn't see that recommended in the recommended test kits, from what I read it is a separate testing kit. When I use pool calculator there is a space to enter borate level - which I have set at 0 current 0 target.
2. Is there something from our water treatment that would be keeping the PH so low without a change after adding borax?
3. Do I just keep adding borax per testing results/pool calculations until the PH is up to level?
(I now believe I should have adjusted the PH FIRST after the initial fill, before adding bleach or cya - is this correct? I couldnt find steps for starting up even after searching threads.
