Bromine sanitation works in two stages: a reservoir of bromide ions in the water (the "bromide bank"), and an oxidizer that converts those ions into active sanitizer. The Reserve & Renew system splits these two stages into two products, which is what makes it completely chlorine-free — unlike bromine tablets, which use chlorine as the built-in oxidizer.

Reserve (Part 1) is liquid sodium bromide. When added to spa water, it dissolves into sodium ions and bromide ions, establishing a stable bromide reserve. On its own, this reserve does nothing — bromide ions are not a sanitizer. They simply sit in the water, dormant and stable, waiting to be activated. This is why Reserve carries no disinfectant claim: it's the fuel, not the fire.

Renew (Part 2) is a non-chlorine oxidizer (potassium monopersulfate). When added to water containing a Reserve-established bromide bank, the oxidizer converts dormant bromide ions into hypobromous acid — the active sanitizing form of bromine that kills bacteria, viruses, and algae on contact. As the active bromine does its sanitizing work, it reverts back to bromide ions and returns to the reserve, where it waits to be reactivated by the next dose of Renew. This regenerative loop is the system's signature efficiency: the same bromide gets used over and over, activated fresh each time you shock with Renew.

Because there's no chlorine anywhere in the cycle — the oxidizer is potassium monopersulfate, not a chlorine compound — the water never develops chlorine odor, chloramine irritation, or the "pool" feeling. The target active bromine range for this system is 1–3 ppm, slightly lower than tablet-fed bromine systems because the reserve is continuously reactivated rather than relying on a slowly dissolving tablet.

Pro Tip: Always add Metal Gon before establishing your Reserve bromide bank at a fresh fill. Sodium bromide solutions can react with dissolved metals in fill water (iron, copper) and contribute to staining if metals aren't sequestered first. The correct fresh-fill order is: balance pH and alkalinity → add Metal Gon → add Reserve → add Renew to activate. Getting the sequence right at startup prevents staining problems that are difficult to reverse later.

Fresh Fill / Start-Up

1. Fill the spa with fresh water and turn on the filtration system.
2. Balance total alkalinity (80–120 ppm) and pH (7.2–7.8).
3. Treat the spa with Metal Gon according to its label directions — especially important for well water or fill water with metal content.
4. Add 4 oz. of Reserve per 250 gallons of spa water directly into the spa while the water circulates, to ensure rapid and thorough distribution.
5. Circulate for 15 minutes with the cover off.
6. Add Renew according to its label directions to activate the bromide bank into active bromine.
7. Test with spa test strips. Target active bromine: 1–3 ppm.

Weekly Maintenance

1. Add 1 oz. of Reserve per 250 gallons of spa water weekly to maintain the bromide bank.
2. Add Renew per its label directions to keep active bromine in the 1–3 ppm range.
3. Test water chemistry with spa test strips and adjust as needed.
4. Maintain ideal ranges: alkalinity 80–120 ppm, pH 7.2–7.8, active bromine 1–3 ppm.

Maintaining the System

The bromide bank gradually depletes over a fill cycle through splash-out, filter backwashing, and water replacement. The small weekly Reserve dose replenishes what's lost, keeping the bank at full strength so each Renew dose can activate adequate bromine. When you drain and refill, the bromide bank resets to zero — so you re-establish it with the full 4 oz. per 250 gallon startup dose each time.

Storage & Handling

• Store in original container in a cool, dry, well-ventilated area
• Keep tightly closed when not in use
• Protect from freezing
• Keep out of reach of children and pets
• Do not mix with other chemicals in undiluted form — always add directly to spa water

Pro Tip: The Reserve & Renew system is the most comfortable water most spa owners ever experience — but it requires discipline on the weekly cadence that tablet systems are more forgiving about. Because the bromide bank needs regular replenishment and Renew needs regular activation, skipping weeks lets active bromine fall to zero faster than a tablet floater would. Set a recurring weekly reminder (most owners pick the same day they test water) and the system runs beautifully. Treat it casually and you'll chase low sanitizer readings. The comfort payoff is worth the routine.
