Chemicals are good, so why are my eyes irritated?

I never add baking soda. I always have to add muriatic acid to keep the PH from going to 8. No calcium chloride has been added. Also, I only use Sodium Hypochlorite as my source of chlorine. 10% solution in one gallon jugs from Home Depot.

The water was replaced three weeks ago so the salt level would be very low. The old water was in there for 15 years based on what the previous owner told me.

I have been thinking about adding salt before, and based on what you've said I going to do it. After we get a few rust spots fixed where the rebar is rusting I'll drop a hundred pounds of water softener salt in and "see" how it feels. I'll need to have a salt test in place before I do this. Any recommendations?

Thanks

Phil
