FROG® Maintain Non-Chlorine Shock 2 oz | 15-Min Reentry

FROG® Maintain is a single-pouch, pre-measured non-chlorine shock designed to keep spa water crystal clear with a quick monthly oxidizing treatment. One 2 oz pouch treats up to 250 gallons. Pour, circulate for 15 minutes, and the hot tub is ready to use again — no waiting hours for chlorine to dissipate. The reason "maintenance shock" matters: even with the best sanitizer program, microscopic organic contaminants build up in spa water over time — sweat, body oils, cosmetics, hair products, dust, pollen. Sanitizer kills bacteria, but it doesn't fully eliminate these non-living contaminants, which gradually turn water dull, hazy, or smelly. Shocking is the process of oxidizing those contaminants out of the water, restoring sparkle and removing odors. Most spa owners shock monthly (or after heavy use) as a normal part of maintenance. What makes FROG® Maintain different from a typical hot tub shock: it's chlorine-free. It uses Potassium Peroxymonosulfate (MPS) as the oxidizer — a different chemistry that does the cleaning work without adding chlorine to your water, and without leaving behind cyanuric acid (CYA) that gradually builds up in spas using dichlor shocks. Less downtime, no CYA buildup, no extra chlorine smell. Just clearer water. Why Monthly Shocking Matters: Sanitizer keeps bacteria in check, but only oxidation removes the dead-skin, sweat, lotion, and organic residue that accumulates from regular use. Skip your monthly shock and water gradually dulls — even though it's still sanitized. Owners who shock on schedule report water that looks better, smells better, and goes longer between full drains.
