High Ph yet Low Total Alkalinity - now what?

[PoolDoc]

thx.

Great explanation & info! Many thanks!

Update: luckily I waited till I heard back. Glad I did. We had a few days of serious ran (4+") here in the Balt. Wash. area. My Ph dropped to 7.0 - 7.2 from 7.8 but I did add two 4lb boxes of baking soda. Numbers seem pretty good now. Ph is 7.4 & TA is 90. FC has slooowly dropped to about 7.5 ppm. No CC. I guess the water was pretty free if organics. Cya is up to about 30. Calcium hardness up to 320.

I guess it's best to leave well enough alone for now. Water is crystal clear. Thanks again for all your expert help.

Looks pretty good. One comment I would make is that your calcium hardness is climbing pretty quickly. I assume you are shocking with cal-hypo. You want CH to be between 200-400. If it gets too high, you can have issues with cloudy water. So, you may want to switch to liquid chlorine at some point.

Thanks for the I input Watermom. Is Clorox bleach ok? Right now I have my chlorine tab dispenser turned off till the FC drops more.

Yes, as long as it is plain bleach. No scented stuff, etc. Actually many of us use Walmart's generic bleach which is cheaper than Clorox.
