SpaPure Brom Bank | Spa Sodium Bromide Reserve

• 1 x SpaPure Brom Bank (1 pint / 16 fl oz, liquid sodium bromide)

• Establishes the bromide reserve — builds the bromide bank a bromine spa needs to function
• Fast bromine startup — brings a fresh fill up to a protective bromine level quickly
• Eliminates downtime — no waiting days for tabs to slowly build the reserve on their own
• Liquid formula — pours in and dissolves instantly, no granules to settle
• No chlorine odors — keeps your spa fully bromine-based
• Essential at every refill — use on the initial fill and after every drain-and-refill

Brom Bank adds sodium bromide to the water, creating a reserve of bromide ions. On their own, those bromide ions are inactive — they aren't a sanitizer. But once your brominating tabs (or a shock) introduce an oxidizer, that oxidizer converts the bromide reserve into active bromine that sanitizes the water. The more reserve you've banked, the faster and more steadily your bromine level establishes.

This is also why bromine is so efficient once it's running: as active bromine gets "used up," it reverts to bromide and rejoins the bank, ready to be reactivated again by your next shock. Brom Bank simply gives that cycle a full reserve to start from, instead of waiting for the tabs to build it slowly.

Pro Tip: Remember the order: bank, then tabs. Balance your water, add Brom Bank to establish the reserve, then load the brominating tabs into your floater or feeder. Adding the tabs first without a bromide bank is what leaves a fresh fill under protected — the sequence is what makes bromine work.

Never mix different products together in the same bottle or pail. Add this product directly to the spa water. Use when filling your spa for the first time and whenever the spa has been drained and refilled. Add Brom Bank before dispensing bromine tablets. For reference, 1 capful = 1/2 ounce.

1. Balance the water (pH and total alkalinity) to the proper ranges.
2. Turn on the circulation system.
3. Add 2 ounces per 100 gallons of spa water to establish the bromide reserve.
4. Introduce the bromine tablets to the spa (in a floater or feeder) and follow the recommendations for your sanitizer to bring the bromine level into range.
5. Repeat the Brom Bank step each time the spa is drained and refilled.

Pro Tip: Don't re-dose Brom Bank weekly — it's not a maintenance additive. Once the reserve is established on a fresh fill, your tabs and shocks keep the bromide cycle going. You only rebuild the bank when you start over with fresh water, so a single bottle goes a long way across multiple fills.

SpaPure Brom Bank is for spas sanitized with bromine. It's designed to work hand in hand with SpaPure Brominating Tabs — Brom Bank establishes the reserve, the tabs maintain the bromine level — and with an oxidizing shock, which reactivates spent bromide back into active bromine.

Balance your pH and total alkalinity before dosing, and use bromine test strips to confirm your level. Because it's a bromide builder rather than a sanitizer, it's a startup and refill product, not a daily additive. Never mix it with other chemicals in the same bottle or pail; add it directly to the spa water.
