Leisure Time Replenish | Multi-Action Shock

• (1) Leisure Time Replenish — 2 lb (32 oz) fast-dissolving granular dual-action shock
• Child-resistant cap with measured-pour opening
• Full dosing chart and application directions printed on the bottle label

• Dual-action chemistry — 72% MPS for oxidation + 15% sodium dichlor for sanitizer boost in a single dose
• Built-in pH buffers — does not disrupt water balance like unbuffered shocks can
• Built-in clarifiers — helps maintain water sparkle alongside oxidation and sanitization
• Ideal for mineral cartridge systems — provides the periodic chlorine boost mineral systems are designed around
• One product, three jobs — shock, oxidize, and sanitize in a single weekly application
• 15-minute spa return time — back in the tub within minutes of dosing
• Fast-dissolving granular — no pre-mixing required, dissolves in seconds with pump running
• Eliminates bather waste, body oils, and organic contaminants through MPS oxidation
• Boosts sanitizer residual — each 1 oz. dose adds approximately 2 ppm free chlorine to 300 gallons
• Made in the USA by Leisure Time, a trusted name in spa chemistry for over 40 years

Spa water care actually has three separate jobs happening at once. Sanitization — killing bacteria and viruses — is what chlorine, bromine, and mineral systems do. Oxidation — breaking down body oils, sweat, lotions, and the chloramines/bromamines that build up between soaks — is what shock products do. Clarification — keeping water visually sparkling — is what clarifiers do. Most shock products handle one of these jobs well. Replenish is engineered to handle all three in a single product, which is why the formula is more complex than a simple chlorine or MPS shock.

The 72% potassium monopersulfate (MPS) is the same active ingredient as Leisure Time Renew. MPS is a powerful, fast-acting oxidizer that breaks down organic contaminants into harmless byproducts and burns off combined chloramines and bromamines that have built up since the last shock. This is the "non-chlorine" portion of the shock — it works mechanically through oxidation without adding chlorine to the water.

The 15% sodium dichlor is the same active ingredient as Leisure Time Spa 56 — but at a much lower concentration. Its job in Replenish isn't to be a primary sanitizer; it's to deliver a measured chlorine boost during shock. For mineral cartridge systems (which release low continuous levels of silver and copper ions but rely on periodic chlorine top-ups to handle bather load), the dichlor in Replenish provides exactly the chlorine residual the system was designed around — without requiring a separate chlorine shock product. Each 1 oz. dose adds approximately 2 ppm of free chlorine to 300 gallons of water.

The built-in pH buffers prevent the chemistry swings that can happen with unbuffered shocks — particularly important when using a hybrid formula where MPS and dichlor each have slightly different pH impacts. The built-in clarifying agents help newly oxidized particles aggregate so the filter can capture them, restoring water sparkle in the same dose that handles oxidation and sanitation.

Pro Tip: Replenish is not compatible with biguanide sanitizer systems (Baqua Spa, SoftSoak). The 15% dichlor content means it contains chlorine — and chlorine cannot be combined with biguanide chemistry under any circumstances. If you're running a biguanide spa, use a biguanide-specific shock product. For all other sanitizer programs (chlorine, bromine, ozone, mineral, salt-generated chlorine), Replenish is compatible.

Weekly Maintenance Shock

1. Turn on the spa's circulation system and remove the cover.
2. Add 1 to 1½ oz. of Replenish per 300 gallons of spa water (approximately 1.5 oz. for a typical 400-gallon residential spa).
3. Broadcast the granules uniformly over the surface of the spa water with the pump running.
4. Continue circulation with the cover off for at least 15 minutes.
5. Test residual chlorine after circulation. Target re-entry range: 3–4 ppm.
6. Spa is ready to use 15 minutes after application, once chlorine residual is within range.
7. Repeat weekly for routine maintenance.

After Heavy Bather Use

1. Apply Replenish immediately after parties, multiple consecutive soaks, or any session with elevated bather load.
2. Use the standard 1–1½ oz. per 300 gallons dose.
3. Heavy bather loads can consume oxidation capacity quickly; an immediate post-use shock prevents the next-day cloudy water that often follows heavy use.

Cloudy or Hazy Water Recovery

1. For visibly cloudy or dull water, apply Replenish at the standard maintenance dose.
2. Run circulation with the cover off for 15 minutes.
3. Most clarity issues resolve within 24 hours of a single proper shock.
4. If cloudiness persists, address underlying water balance (pH, alkalinity) before re-shocking.

Storage & Handling

• Store in original container in a cool, dry, well-ventilated area, away from direct sunlight
• Keep tightly closed when not in use — granular oxidizers absorb moisture and lose potency if left open
• Keep out of reach of children and pets
• Never mix Replenish with other chemicals in dry form — including chlorine, bromine, biguanide, acids, or other oxidizers. Concentrated mixing can cause violent reactions or fire. Always add directly to spa water.
• Store separately from acids, oxidizers, and organic materials

Pro Tip: Apply Replenish with the spa coveroffand leave it off for the full 15-minute circulation. The oxidation reaction releases gas that needs to vent out of the spa, not trap into the cover where it can degrade the foam, the underside vinyl, and the headrest pillows over time. This applies to any shock product, but it's especially important with hybrid formulas like Replenish where multiple reactions are happening simultaneously.
