BioGuard Pool Complete 911 | Emergency Clarifier

BioGuard Pool Complete 911 is the emergency version of BioGuard's clarifier line — built for water that's gone well past hazy into genuinely cloudy or swamp-like. It combines advanced enzymes and clarifiers to clear water roughly twice as fast as leading clarifiers, with visible results in a matter of hours.

The enzyme component is what separates 911 from an ordinary clarifier, and it addresses a problem most people don't realize they have. A conventional clarifier gathers suspended particles into clumps the filter can capture — it's mechanical, and it works well on dust, pollen, and fine silt. But a large share of what makes a neglected pool look like a swamp is non-living organic waste: body oils, sunscreen, lotions, cosmetics, and decomposed organic matter. That material is dissolved and emulsified rather than suspended as particles, so a clarifier has nothing to grab onto.

Enzymes break that organic load down into smaller compounds the filter can remove or that leave the water entirely. Pairing them with clarifiers means the product handles both categories of contaminant at once — the particles a filter can't catch and the organic waste a filter can't touch.

It's dosed heavily at 2 fl oz per 1,000 gallons — five times the rate of BioGuard's weekly maintenance product — which is what makes it a corrective product rather than a maintenance one. It's used at pool opening, after a period of neglect, or any time during the season when water has gotten badly away from you.

Worth being clear about the boundary: this clears non-living contamination. If your pool is green with algae or has failed sanitation, that needs shock and an algaecide first. 911 handles what's left afterward, and it handles it fast.
