Pro Tip: Acid lowers both pH and Alkalinity. If your alkalinity is already in the 80-120 range, be careful not to over-add acid. If you drop it too low, use our Baking Soda Calculator to bring it back up.

Frequently Asked Questions
Can I mix muriatic and dry acid?
NEVER mix different types of acids (or any chemicals) in concentrated form. If you are switching types, wait until the first dose has fully circulated for 24 hours.
Does dry acid damage salt cells?
Yes, long-term use of dry acid can lead to sulfate buildup, which is detrimental to the life of salt chlorine generator cells. Muriatic acid is preferred for salt pools.
Muriatic Acid vs. Dry Acid (pH Down)
Muriatic Acid is a powerful liquid (Hydrochloric Acid) that works quickly but can be hazardous to handle and store. Dry Acid (Sodium Bisulfate) is a safer, granular alternative but is often more expensive per dose.
Safety Reminders
When handling muriatic acid, always wear gloves and eye protection. Never mix different types of acids or chemicals together. Always add acid to water, never water to acid.
