Hi all,
I'm now thinking about adding borates to my pool and spa. Should I assume 0 to start, or should I test with the strips first?
 
Why do you think you need to add borates?

Update- read the above link so disregard. Is your ph rising quickly?
 
For a number of reasons. My Spa is not covered and is pretty big (10ft diameter), so I'm adding bleach almost daily (I used the dichlor/bleach method) and the ph does rise faster than I'd like. I also like the idea of the "silkiness" for the hot tub.

I would also like the silkiness feel I read about but anecdotally on this forum a majority of people say it's not really noticeable.

I think @jkarn can give us a A vs. B comparison since he has two independent bodies of water and will add borates to one of them first and tell us what differences people feel.
