Following instructions from this forum, I have done a 1/2 drain and refill with city water. Would like some guidance as to what to do next in migration to BBB.
Prior to Drain.. Pool was clear, but previously I had a couple of algae attacks and was using pool store advice with pucks and shock, with limited success and very high CYA. Ordered Taylor k-2006 and here are numbers prior to drain.
----------------------------------------------------------------
FC 2.0
CC 0.5
PH 7.4
TA 150
CH 70
CYA well over 100 (note: on Taylor it's half way between the 100 mark and the bottom of the tube)
------------------------------------------------------------------------
Just for info, I measured the city tap water prior to the refill.
------------------------------------------------------
FC 1.6
PH 7.3
TA 20
CH 30
CYA 0
-----------------------------------------------------
Now here are my numbers after the drain and re-fill
----------------------------------------------
FC 1.0 right after refill
FC 5.0 after 2 gallons of bleach
CC 0.4
PH 7.6
TA 80
CH 50
CYA greater than 100 estimating 130
----------------------------------------------------
Looks like several more half drains and refills to get CYA where it needs to be
Would like some direction and help to ensure a smooth transition to keep me out of trouble.
