Thursday, June 2nd 6:45 a.m. (Day 8)
Throughout the day on Wednesday the FC level was keep elevated by adding multiple dosages of chlorine (bleach 6%) based on the records from the prior 2 days – with only 1 water test was completed (8:30 p.m.).

Changing the sand within the filter went OK, what a mess! - and it took longer then thought it would. Backwashed & rinsed, restated circulation at 4:30 p.m. – with some visible sand later in the pool? - not sure why?

The following readings were taken at 6:30 p.m. (2 hrs after re-starting pump)
WT = 83 deg.
FC = 0.5 ppm (really low based on the reading this a.m.?)
CC <= 0.5 ppm
pH = 7.1
TA = 45
CH = did not test
CYA = did not test

With the pH at borderline low, I will add the following;
pH - 7:30 p.m., add 1 lb of soda ash (Borax)
TA – 9:00 p.m., add 2 lbs of baking soda (A&H)
FC – 10:30 p.m., add 1.42 gal of chlorine (bleach 6%)

Plans for early a.m. on Friday include 1) vacuum sand from bottom of pool, 2) complete a comprehensive water test, and 3) almost certainly add 1-2 lbs of stabilizer / conditioner (via sock in strainer).

Any and all comments with regard to correct steps to balance our pool, now that the BaquaGoo is finally gone, would greatly appreciated and “Thank you”
