When a pool turns milky, dull, or opaque after algae treatment, storms, or heavy debris load, normal filtration often isn’t enough. GLB Drop n’ Vac is a professional-strength pool flocculant designed for these exact situations. Instead of slowly filtering fine particles over days, Drop n’ Vac forces microscopic debris to bind together, sink to the pool floor, and be physically removed.

This is not a cosmetic clarifier and not a weekly maintenance product. GLB Drop n’ Vac is a corrective solution used when water clarity must be restored quickly and decisively.

For service professionals and experienced pool owners, this product is the reset button when filtration alone can’t win.

What GLB Drop n’ Vac Is Designed to Fix

Cloudy pool water is often caused by particles that are too small for filters to capture efficiently—especially after algae dies, dust storms roll through, or construction debris enters the pool. Even balanced chemistry won’t solve the issue if those particles stay suspended.

GLB Drop n’ Vac addresses this by removing the debris from the water entirely, not just trapping it.

Common Problems It Solves

• Severe cloudiness after algae treatment

• Dust, pollen, or silt overwhelming the filter

• Post-storm pool cleanup

• Pools that won’t clear despite proper chemistry

• Fine debris bypassing sand or DE filters

How Drop n’ Vac Works (Flocculant vs Clarifier)

It’s important to understand the difference between a clarifier and a flocculant.

Clarifiers bind tiny particles together so your filter can catch them over time. Flocculants like GLB Drop n’ Vac take a stronger approach by binding those particles into heavy clumps that sink immediately.

Once settled, the debris must be vacuumed directly to waste, completely removing it from the pool system instead of recirculating it.

This makes Drop n’ Vac ideal for emergency cleanup—but inappropriate for routine use.

Why Filtration Alone Sometimes Fails

Filters are designed with micron limits. When debris is smaller than what the filter media can trap, it keeps circulating—no matter how long the pump runs.

In these situations:

• Filter pressure rises without clarity improving

• Clarifiers act too slowly

• Chlorine demand stays high

• Water never fully clears

GLB Drop n’ Vac bypasses filtration limitations entirely by forcing debris out of suspension.

Why This Matters

• Saves hours or days of run time

• Prevents repeated chemical additions

• Restores clarity fast

• Stops cloudy-water loops

When to Use GLB Drop n’ Vac

GLB Drop n’ Vac should be used only when conditions call for it, not as a preventative product.

Best Use Scenarios

• After killing visible algae

• After heavy wind or dust storms

• Pools opened with extreme cloudiness

• Filters that can’t keep up with fine debris

• Emergency clarity restoration

It is not recommended for cartridge filters unless vacuum-to-waste is possible.

Critical Application Notes

Correct use is essential for success. Improper circulation or aggressive vacuuming can re-suspend debris.

Key principles:

• Follow dosing instructions carefully

• Circulate briefly, then shut the pump off

• Allow debris to settle fully (often overnight)

• Vacuum slowly and gently to waste

• Do not brush before vacuuming

• Clean the filter after treatment

When used properly, one treatment is often enough to restore clear water.
