After getting my FC up to 4 and CYA at 50 I have watched the FC level drop over the last 7 days as follow:
3.5 on 7/13,
2.5 on 7/15, and
1.2 on 7/17.
Chlorinator had been running at 65%. When I saw the 1.2 FC number last night I turned super chlorinate on and ran the pump all night.
Today I am reading 0 to .2 FC.
Salt level is 3300,
PH is 7.5 and
ALK is 60
I thought getting the stabilizer back in there (after getting a bad reading from a pool store previously) and doing my own testing from now on I'd be set. But, losing FC obviously.
Any suggestions on what to check next?
And, I guess I should get some liquid chlorine in the pool to catch things early?
