Filter is Hayward C-800 Star Clear Filter. Pump is A.O. Smith Centurion Switchless Motor

Ordered one of the test kits you recommended and also found a test kit at my mom's.

Chlorine test didn't show any trace of chlorine
Ph was normal
Total Alkilinity test says I need to add 1 1/4 gallons of muriatic acid.

I'm starting to think there's not enough salt in the pool. The water doesn't taste nearly as salty as I remember it tasting when the pool was sparlking clear last year. The low salt code is on the salt to chlorine converter too.

Should I still go ahead with adding the bleach? Do I still need to get the other testing kits from walmart as well while I wait on the other test kit?
