I was just advising someone to play with the Pool Calculator to get familiar with it and so I started playing with in with my pool values.
My pool is not salt, as far as I know, but then I've added so much bleach to it in 18 months that it may have a lot of salt in it now. I noted the other day that I found it easy to float, which makes me think that maybe it is a bit salty. I can't taste any salt however.
I recall that someone said that a non-salt pool might still have 1500 ppm of salt.... so I added that to my values in the Calculator and WOW -- suddenly my CSI is at -.51
So, should I be testing for salt? Should we all be testing for salt? It seems to make a difference, at least to me since I'd run TA to the low side to keep pH in check, then started using tabs to get CYA up. If I assume no salt, the CSI is fine at -.37.
