OK, I completely connected our new filter yesterday, after about a month with no filter. 24' round ag 13500ish gallons. Last night I shocked with bleach. This morning I tested and the numbers were.(hth 5way drop kit)

CL/BR-way high, over the 5/10 on the vial
PH- lower than 6.8
alk- 40
cya-80-90
hardness, no change in water color




This evening, the readings were
cl/br- 5/10
ph- lower than 6.8
alk dropped to 30
cya no change 80-90
hardness no change in water color


After the evening reading I added about 1 1/2 pounds on borax and tested 3 1/2 hrs later with these results.


CL/BR 5/10
ph just lower than 6.8

Whats your thoughts, am I on the right track??? Can I keep adding borax in small amounts to get to the right level?
