I have a salt water pool with low ph. Any suggestions?
Thanks
Low PH

calcium hypocloride will lower your pH.
so, your only choice for the rest of the season is liquid bleach.
Cal Hypo will increase your pH. It has a pH of 11.7 and sodium Hypo (bleach) has a pH of 13
Just get a little pH increaser and fix the problem directly. It will be a good fix and you will have it when you require it again. Its cheap and does the job and available most anywhere that pool chemicals are sold.
The Boric acid will help support your pH and may the water feel silky. It will also help raise the pH
Chlorine (bleach) does not cause pH to rise after use

Actually, it turns out that Sodium Hypochlorinte (chlorinating liquid or bleach) or Calcium Hypochlorite (Cal-Hypo) only temporarily raise the pH. The chlorine will get broken down by sunlight or will oxidize organics or disinfect or turn ammonia into nitrogen gas -- all of which are acidic processes. The net effect is no change in pH. Now, chlorinating liquid, and to a lesser extent bleach, do add a small amount of sodium hydroxide (lye) for stability so that will result in a small net increase in pH, but not very much.
