SpaPure Brom Bank | Spa Sodium Bromide Reserve

SpaPure Brom Bank is a liquid sodium bromide that builds the bromide reserve — the "bromide bank" — that every bromine-sanitized spa needs to work properly. It's the essential first step when you start up a bromine spa or refill it with fresh water, added before your brominating tablets.

Here's the part that trips up new bromine owners: brominating tabs alone are slow to protect a fresh fill. Bromine works by maintaining a reserve of bromide in the water that gets converted to active sanitizer — and on brand-new water, that reserve doesn't exist yet. Without it, a fresh fill can sit underprotected for a long time while the tabs slowly build the bank on their own. Brom Bank establishes that reserve instantly, so your bromine level comes up fast and the spa is protected from the start.

It's not a sanitizer on its own — it's the foundation that makes your bromine sanitizer work. Use it at every fresh fill and your bromine system runs the way it's supposed to, with no chlorine odors and no frustrating startup downtime.
