Bleach/Salt Question

[dschribs]

I've read that bleach contains salt.

If I use bleach as my only source of chlorine, do I ever need to worry about or test the salt levels in my pool?

Look at the bottom where it says "effects of adding chemicals". Here you can see how much salt each addition of bleach will add.

Why would you worry about them anyway, several of us have purposely added lots of salt to our pools!

No, it is a miniscule amount. The pool calc will tell you exactly how muxh it adds.

Also keep in mind that ANY source of chlorine will increase the salt level because when chlorine gets used/consumed it turns into chloride (as in sodium chloride, table salt). Bleach and chlorinating liquid add extra salt upon addition. For every 10 ppm Free Chlorine (FC) added by bleach and chlorinating liquid, it will increase salt (after the chlorine is used/consumed) by 17 ppm. So if you have 2 ppm FC per day chlorine usage, the salt level will increase by 100 ppm per month if there is no water dilution. Not a big deal since salt is relatively innocuous, especially compared to CYA or CH which would build up from stabilized chlorine or Cal-Hypo, respectively.
