new results - ph high and cya low

[9needawin]

FC = 4.5
ph = 8
TA = 90
CYA = 40

Can I correct PH and CYA at the same time? I have the MA to add but it is really hot this weekend and would like to swim if possible. Should i just correct PH at the end of the day and then add CYA tomorrow to bring it up?

Yes, you can correct both today, just not literally at the same moment

I suggest lowering PH to around 7.2 this time, which will help bring down the TA.

You can swim half an hour, with the pump running, after adding acid. There is no wait to swim after adding CYA.

Thanks Jason!

The CYA in liquid form does not alter the pH, but the granular/powder form of CYA does lower pH as well. At the bottom of the pool calculator you can enter the amount of the CYA you would add to your pool and it will tell you how it will affect the pH.

Jason,
Is that 30 min wait time the same as after adding dry acid, (sodium bisulfate) or is that longer? Thanks!
