Description

Leisure Time Reserve is a liquid sodium bromide solution and the foundation of the chlorine-free Reserve & Renew sanitizing system. Active chemistry: 32.18% sodium bromide in a clear, fast-mixing liquid. Reserve establishes a stable “bromide bank” in your spa water — a reservoir of bromide ions that sits dormant until activated. It carries no disinfectant power on its own; it’s Part 1 of a two-part system, and when Leisure Time Renew (Part 2) is added, the bromide bank converts into active bromine sanitizer.

Chlorine-free water tops the wish list for many hot tub owners. Chlorine sanitizes effectively, but some people dislike the smell, the effect on sensitive skin and eyes, and the “pool” feeling it gives hot tub water. The Reserve & Renew system delivers complete, reliable sanitation with zero chlorine — and without the unpleasant side effects associated with other non-chlorine approaches. The result is soft, odorless, gentle water that still kills bacteria, viruses, and algae as effectively as any conventional system.

The design is elegant: Reserve loads the water with a bromide reserve that stays stable and ready. Each time you add Renew oxidizer, it activates a portion of that reserve into active bromine, which sanitizes the water and then reverts to bromide — going back into the bank to be reactivated again. This regenerative cycle means less total chemical use, no chlorine, and a consistently comfortable soak. A 32 oz bottle of Reserve covers fresh fill plus weekly maintenance for a typical residential spa through a full fill cycle.

Pro Tip: Reserve and Renew are a matched pair — neither works without the other. Reserve alone has no sanitizing power; it’s just the bromide bank sitting dormant. Renew alone (without a bromide bank established) is just a non-chlorine oxidizer with nothing to activate. Together they form a complete chlorine-free sanitizing system. If you’re setting up a chlorine-free spa, you need both products from the start — buying one without the other leaves you with an incomplete system and unsanitized water.
