TA Test - Me vs. Pool Store(s)

[waterbear]

Hmmm...I'm confused, My Taylor kit says to add R-0009 until it changes from green to red. Why the difference?

Taylor has a LOT more info on their website. This is where it says to keep adding drops until one more drop doesn't produce further change and then not count the last drop.

Thanks, Evan. That's a fine detail I didn't know.

The moral is you MUST process what pool store guys say and do a reality check on them.
How can a pH of 7.8 be low?
Saying that the T/A of 75 would could acidity to eat your copper means the PSG (Pool Store Guy/Gal) doesn't know what T/A is.

Hey! I like that! Don't get Poolstored by a PSG !

Yup - that is exactly what I thought. I will stick with my testing and try to bring the TA by splashing and pointing the jets up at the surface.

I will have to test my CYA - I doubt it is as high as 80, but I do have some stabilizer hanging around that I can add.

Thanks all.

Splashing and pointing your jets up will raise the pH, not affecting the
TA. If you're trying to lower your TA, you use acid to drop the TA and the pH will drop with it....then you aerate the water with splashing and upward jets to raise the pH back up without raising the TA.

Thanks for clarifying.
