Should I be concerned that my FC is so high?

[jewing]

My numbers are:

FC = 22
CC = 0
PH = 8.0
TA = 120
SWG = 3200
CYA = 60

My PH has gone up in the last few days. Most likely due to us using the pool more. My TA has gone up to. But my FC went up from 15 to 22. I shocked my pool a few weeks ago and have been running the SWG at about 60%.


I turned my SWG down to 20% this morning to see if the FC would lower. Is the PH related to the FC at this point? I want to wait until the FC goes down before I adjust anything.

Any suggestions?

High FC causes a discrepancy in the pH test so it reads a bit falsely high. You should be fine right where you are.

Test pH again once FC gets down below 10 ppm.

My TA is high too. Should I wait until the FC is below 10 to do anything about that also? Does a high PH or high FC impact TA?

The TA test is not affected, but to lower it you have to follow the process described in Pool School. And to do that you have to be able to test pH.

ok. that makes sense. Thanks. I will just sit tight and wait for the FC to come down then. Pool is sparkling so no real worries. Appreciate the quick response.

You can turn your swg off. No need for it to be generating FC until you're back in range for chlorine.

Then you can move on to pH and alkalinity.
