Turn Cloudy Water Into Crystal Clarity

Natural Chemistry Pool First Aid blends concentrated enzymes with a fast-acting polymer clarifier to tackle pool water contamination, clogged filters, and waterline build-up. The formula is designed to break down non-living organics — like dead algae, oils, pollen, paint, antifreeze residue, and even vandalism traces — quickly and effectively.

Key benefits at a glance

  • Clear water, faster: combining SMARTZyme technology with a clarifier to restore clarity quickly.
  • Fast-acting, often without scrubbing: dissolves organic residues in the water and helps improve filter performance.
  • Clear filters: helps remove oil and other organics clogging filters to optimize circulation.
  • Sanitizer-agnostic: compatible with all sanitizing systems for versatile pool care.
  • Non-toxic and biodegradable: safer for pool users and the environment, with reduced foaming and a softer feel to the water.

How it works in your pool

The enzyme blend targets non-living organics, speeding up their breakdown so they’re easier for your filtration system to remove. The polymer clarifier then helps particles join larger clumps so they can be trapped by the filter, resulting in clearer water.

How to use

For best results, add as directed: 2 oz per 1,000 gallons; 1 capful treats 2,000 gallons. Use every two days until water is clear. Do not use immediately before or after shocking; avoid shocking during the 48-hour period after application.

What it tackles

  • Dead algae and organic residues
  • Pollen, oils, and spills
  • Waterline buildup and residues
  • Oil and organic clogs in filters

Why this matters for your pool

With regular use, pool first aid can reduce the need for extra chemicals and heavy shocking, supporting a cleaner, softer pool experience. It’s compatible with all sanitizers and designed to support overall water care without complicating routines.
