FROG® Maintain 16 oz | Bulk Non-Chlorine Shock

FROG® Maintain - 16 oz. is the bulk-container version of FROG's non-chlorine maintenance shock. Same chemistry, same use case, and same 15-minute reentry as the single-pouch 2 oz version — just packaged as a value-size container that gives you roughly eight shock doses for a standard 250-gallon hot tub instead of one. The 16 oz container is the smarter buy if you actually use FROG® Maintain on the recommended schedule. Most spa owners shock monthly, plus after heavier use — so a 16 oz container at one 2 oz dose per shock covers roughly 8 months for a typical 250-gallon hot tub. The single-pouch version is great for trying the product, traveling, or as a one-time buy. The bulk container is what you want as your standing supply. Chemistry-wise it's still chlorine-free MPS-based shock — Potassium Peroxymonosulfate, the same active ingredient as the 2 oz pouch. That means no cyanuric acid added to your water, no chlorine smell after dosing, and a 15-minute reentry time instead of the hours you'd wait after a dichlor shock. The bulk size doesn't change any of that — it just lets you stop reordering single pouches every month. Why Bulk Pays Off: Per ounce, the 16 oz container costs roughly 60% less than the 2 oz single pouches. If you're going to shock monthly anyway (which is the recommended cadence on any spa), the math of a single 16 oz container is much better than buying eight single pouches over the same eight months. Same product, same chemistry, much better cost-per-shock. Brand FROG®
