Description

Leisure Time Replenish is a multi-functional dual-action shock and oxidizer formulated specifically for spas and hot tubs. Active chemistry: a powerful combination of 72% potassium monopersulfate (MPS) for non-chlorine oxidation and 15% sodium dichlor for sanitizer-boost chlorine — plus built-in pH buffers and clarifying agents. Unlike single-action shock products that handle either oxidation or sanitization, Replenish does both in one dose, which is exactly what mineral cartridge systems and supplemental-chlorine spas were designed to use.

Replenish exists for a specific category of spa owner: anyone running a mineral cartridge sanitizer system (like the FreshWater Salt System, Spa Frog @ease, or any silver/copper mineral cartridge), or anyone who wants the convenience of “one shock that does everything.” Mineral systems work by combining low-level continuous sanitizer release with periodic chlorine boosts — and Replenish is engineered to deliver that combined oxidation + chlorine boost in a single weekly dose. For chlorine-program spas, it’s also a strong option as a “do-everything” maintenance shock that handles both organic load and sanitizer residual in one step.

A 2 lb bottle provides approximately 30 weekly maintenance shocks for a typical residential spa — roughly 6 months of weekly use. Replenish is fully soluble, dissolves in seconds with the pump running, has a short 15-minute spa return time, and includes the pH-buffering and clarifying agents that prevent the chemistry swings other shock products can cause.

Pro Tip: Leisure Time makes three different shock products, and they’re not interchangeable. Spa 56 is pure chlorine — daily sanitizer plus heavy superchlorination. Renew is pure non-chlorine MPS — weekly oxidation with no chlorine added, 15-minute spa return. Replenish is a hybrid of both — non-chlorine oxidation plus a measured chlorine boost in one dose. Pick based on your sanitizer program: chlorine spa → Spa 56 daily + Renew weekly (or just Spa 56). Bromine or mineral cartridge spa → Renew weekly. Mineral cartridge spa needing chlorine boost → Replenish weekly. Replenish is the right choice when you want both oxidation and sanitizer-boost in one product.
