BioGuard Pool Complete 911 | Emergency Clarifier

• 1 x BioGuard Pool Complete 911, 2 liter bottle
• Full manufacturer label with dosing rates, application directions, and safety information

Note on quantity: at 2 fl oz per 1,000 gallons, a 2 liter bottle treats approximately 33,800 gallons — enough for one full treatment on most residential pools. A 20,000-gallon pool uses roughly 40 fl oz per treatment, so a single bottle covers one application with some margin. Badly neglected water may need a second.

Clears Cloudy Water Twice as Fast as Leading Clarifiers

Built for speed when the pool needs to be usable soon rather than eventually. Results are visible in hours rather than over several days.

Advanced Enzymes Plus Clarifiers

Two mechanisms working at once — enzymes break down dissolved organic waste, clarifiers gather suspended particles. Most clarifiers only do the second.

Handles Swamp-Like Conditions

Formulated for the extreme end of the problem, not just routine haze. This is the product for a pool that's been neglected or opened badly.

Eliminates Non-Living Contaminants

Targets the body oils, sunscreen, lotions, cosmetics, and decomposed organic matter that build up in water and dull it in ways sanitizer alone won't fix.

Works at Opening or Mid-Season

Effective whether you're recovering a pool after winter or rescuing one that got away from you in August.

Improves Filtration Efficiency

Converts contamination into forms the filter can actually remove, so material that would otherwise recirculate indefinitely leaves the pool.

Simple Application

Pour directly into the deep end with the pump running. No dilution, no pre-mixing.

Pool Complete 911 combines two different technologies, and understanding the split explains why it works on water that defeats an ordinary clarifier.

Clarifiers handle suspended particles. Much of what makes water hazy is material too fine for a filter to capture — silt, pollen, dead algae cells, precipitated minerals, all measured in fractions of a micron. Those particles carry a slight negative charge that makes them repel each other and stay dispersed indefinitely. Clarifying agents neutralize that repulsion and bridge between particles, gathering them into clusters large enough for the filter to trap on the next pass.

Enzymes handle something a clarifier can't touch. Body oils, sunscreen, lotions, cosmetics, and decomposed organic matter aren't suspended particles — they're dissolved and emulsified organic compounds. There's nothing for a clarifier to gather. Enzymes are biological catalysts that break large organic molecules into smaller ones, converting that load into compounds the filter can remove or that dissipate from the water entirely.

That combination is why the product handles swamp-like conditions. A badly neglected pool has both problems at once: a heavy particle load and a heavy organic load. Treat only the particles and the water stays dull and greasy. Treat both and it clears.

The heavy dose rate follows from the same logic. At 2 fl oz per 1,000 gallons, this is five times the rate of BioGuard's weekly maintenance product — because it's addressing accumulated contamination rather than keeping up with daily inputs.

The 48-hour circulation requirement is the part people shortcut, and it matters. Enzymes need time to break material down, clarifiers need time to gather it, and then every gallon of pool water has to physically pass through the filter for the results to be removed. A typical residential pump takes 8 to 12 hours for a single turnover. Forty-eight hours gives the pool several complete passes, which is what a heavy contamination load requires.

One boundary worth stating plainly: Pool Complete 911 is not a sanitizer, an algaecide, or a shock. It's explicitly for non-living waste. Living contamination — algae, bacteria — needs oxidizing chemistry, and no amount of enzyme or clarifier will substitute.

Pro Tip: Sequence matters on a green pool, and 911 is not the first step. If your water is green or growing algae, you have living contamination, and this product doesn't address it. Shock the pool first with an appropriate oxidizer, add an algaecide, brush the surfaces, and let the chlorine do its work. Once the algae is dead, you're left with a pool full of dead organic material and fine suspended debris — which is exactly what 911 is built for, and exactly when it delivers its fastest results. Using it first on green water wastes an entire bottle and a day of circulation.

Dosage Reference

• 2 fl oz per 1,000 gallons of pool water
• A 10,000-gallon pool uses approximately 20 fl oz
• A 20,000-gallon pool uses approximately 40 fl oz
• A 2 liter bottle treats up to approximately 33,800 gallons
• No dilution required

Before Applying

1. Shake well before using. This product is not intended for oral consumption.
2. Make sure all pool equipment is working properly, including the pump, filter, skimmer, and heater. If needed, backwash and/or clean the filter according to your equipment manufacturer's directions.
3. Note your clean filter pressure so you have a baseline to measure against.
4. If the pool is green or has visible algae, shock and treat with an algaecide first, and let that work before applying this product.
5. Confirm your pool's actual gallon capacity before measuring.

Application

1. Apply this product at a rate of 2 fl oz per 1,000 gallons of pool water.
2. Apply directly into the water while walking around the deep end of the pool.
3. Allow the pump and filter to operate for at least 48 hours after application.
4. Monitor filter pressure throughout and clean or backwash when it rises 8 to 10 psi above your clean baseline. On heavily contaminated water this may happen more than once.
5. Vacuum any settled material from the pool floor.
6. If water remains cloudy after the full 48 hours and a filter cleaning, a second treatment may be warranted.

After the Water Clears

• Retest and rebalance — total alkalinity, then pH, then calcium hardness
• Confirm sanitizer is back in range
• Clean the filter thoroughly one final time
• Switch to a weekly maintenance product so the pool doesn't return to this state

When to Use It

• At pool opening, when winter has left the water cloudy or swamp-like
• After a period of neglect — a vacation, a busy stretch, an equipment failure
• After clearing an algae bloom, to remove the dead organic material left behind
• Following heavy bather loads that have loaded the water with oils and lotions
• Any time water is badly cloudy and you need it usable quickly

Storage and Handling

• Store in a cool, dry, well-ventilated area, out of direct sunlight and protected from freezing
• Keep the container tightly closed and clearly labeled
• Store separately from sanitizers, acids, and oxidizers
• Keep out of reach of children and pets
• Read and follow all label precautions, first aid, and disposal directions before use

Pro Tip: Once the water is clear, switch to weekly maintenance — don't keep an emergency product as your routine. At 2 fl oz per 1,000 gallons, 911 is dosed five times heavier than the weekly maintenance product, and using it as a regular treatment is an expensive way to solve a problem that costs far less to prevent. The contamination it clears accumulates gradually from swimmers, weather, and time, so a light weekly product keeps the pool from ever reaching the point where an emergency treatment is needed. Recover with 911 once, then maintain, and you'll likely never need the emergency bottle again except after a genuine incident.

• Painted surfaces

Sanitizer Programs

• Chlorine pools — fully compatible

Choosing Among the Pool Complete Products

• Pool Complete 911 — the emergency product. Enzymes plus clarifiers at a heavy dose, for cloudy or swamp-like water that needs to clear fast. This product.
• Pool Complete Weekly — the maintenance product. A lighter weekly dose that clarifies, prevents waterline buildup, and removes phosphates so water never gets to the 911 stage.
• Pool Closing Complete — the seasonal product, applied once at closing to prepare water for months under a cover.

The usual pattern is 911 to recover, then Weekly to hold the line.

What It Does Not Do

• Not a sanitizer. Provides no disinfection and maintains no residual.
• Not an algaecide or shock. Living contamination — algae and bacteria — requires oxidizing chemistry first.
• Not a balancer. Cloudiness from high pH or high calcium hardness requires correcting those values.
• Not a substitute for filter maintenance. The filter does the actual removal.

Important Handling Cautions

• Shake well before using. The concentrate settles.
• Never mix with other chemicals. Add products separately, allowing circulation between additions.
• Not intended for oral consumption.
• Expect substantial filter pressure increase during treatment.
