Eye irritation with 7.5 pH and 0 CC?

[drband]

I'm constantly amazed by the info I find here on the forum! Thanks for answering this... I've had the same question for a while...

How do you increase the TDS if it is low? I have a vinyl pool and have always ignored TDS.

Add salt.
Many pool owners add enough to reach around 2000 ppm and report a increase in bather comfort. There has been discussion about this in the past on the forum and on other forums and I don't remember anyone ever regretting adding salt.

Can you post the rest of your readings, like CYA and FC for starters?

That's 2000 ppm of salt, not a TDS reading?

Apologies if I am re-treading old ground. When I search for TDS, it's to short to be used by the search function.

That's correct.
