Howdy,

I just did a full test of my water, first of the season, and my results are attached. I see that I probably need to increase my CYA a bit however my pH is a bit low also. Will adding CYA lower my pH any further? Do I need to add baking soda first to increase it a little? The app suggests 36oz of baking soda to bring it up to 7.6. Also, should I be concerned about the CSI being out of range?

Pool looks great at the moment in terms of clarity but want to ensure I stave off any potential upcoming issues. Only had the pool a year so still learning. Haven’t had to adjust the pH up until this point.

Thanks,
Mike

CSI does not matter to your pool surface. Turn off tracking CSI.

Add some CYA. As you will using liquid chlorine just raise it to 40 ppm for now.

I would not add any baking soda, but if you like, 10 ppm TA worth will likely not hurt.
