Thanks Carl

Pool details: 15'x30' 15k gal rectangle pool tile pool | Pentair Triton II TR60 sand filter | Pentair IntelliFlo VS-3050 variable speed pump, on 3

I'm going to look for the Washing soda, and I need to visit my pool store and get stabilizer (that's the only think I can't seem to measure with my 5-in-one kit now) I realize based on the poolcalculator.com the amounts of baking soda i was adding was way low, added more and new readings below after an hour. Making progress!

Current Readings:
FC = 2 (don't know how to test for CYA levels?)
pH = low about 6.3 (noticeable increase from testing)
TA = 80 (up from 20 by adding baking soda and Borax)
CYA = not sure how to measure w my kit? need Taylor kit?

Isn't the chlorine level suppose to be 2-4, that's what the kit reads? I saw the BBB chart in the forum, but am not clear on how to interpret it. I know it's all based on CYA levels, so knowing that seems a first step.

I plan on buying the Taylor kit, and supporting the community, just curious to understand the diff between it and the 5-stop one I have. Is it the ability to test CYA?

From my tests moving forward...,
1) I need to add more Borax to raise the pH, TA is on the low end but it will increase a bit with Borax, right?
2) slowly add more bleach to bring chlorine levels up a bit (to what tho? I need to know the CYA level first, right?
3) get stabilizer, learn how to test for CYA level, please advise.
