BioGuard Pool Juice Zero | Pool Phosphate Remover

• 1 x BioGuard Pool Juice Zero bottle
• Full manufacturer label with application directions and safety information

Note on quantity: one bottle treats up to 20,000 gallons. Larger pools need proportionally more — a 40,000-gallon pool requires two bottles for a full treatment. Pools under 10,000 gallons should not exceed 16 fl oz in a single treatment regardless of bottle size.

Reduces Phosphates to Near Zero in 24 Hours

Fast corrective action on an accumulated phosphate load, rather than a slow drawdown over weeks of light maintenance dosing.

Combats Constant Phosphate Additions

Addresses the inevitable inputs from source water, ground runoff, and weather — inputs that continue whether you're paying attention or not.

Removes the Nutrient Algae Depends On

Takes away the food source before a sanitizer dip becomes a bloom, which is the difference between a pool that recovers from a hot weekend and one that turns green.

Clarifier and Enzymes Included

Cleans waterlines and maintains sparkling clear water alongside the phosphate removal, so one treatment handles three problems.

Enzymes Break Down Organic Waste

Targets the body oils, lotions, and cosmetics that form waterline scum — dissolved material a clarifier alone has nothing to grab onto.

For All Types of Swimming Pools

Compatible with every common pool surface, filter type, and sanitizer program.

Simple Application

Pour around the edges of the pool with the pump running. No dilution, no pre-mixing, no special equipment.

Pool Juice Zero works on two fronts, and the split explains why it clears things a simple clarifier can't.

Phosphate removal is the primary function. Phosphates in pool water are dissolved and chemically stable. They aren't organisms, so sanitizer doesn't destroy them. They aren't particles, so a filter can't catch them. They aren't volatile, so they don't evaporate. The product works by binding phosphate ions into an insoluble compound — converting them from a dissolved state into a solid particle your filter can physically capture and remove. That's genuine removal rather than suppression: once filtered out, the phosphate is gone until new phosphate enters.

Why that matters comes down to how algae blooms actually start. Algae needs light, warmth, and nutrients. You can't control the first two. Sanitizer holds algae back as long as the residual is maintained — but residuals dip. Sun burns chlorine off, heat accelerates consumption, a party loads the water, a rainstorm dilutes everything. Whether that dip becomes a bloom depends largely on whether food is available. Low phosphates give the pool a much wider margin for the days you aren't perfect.

The enzyme and clarifier components handle a different category. Clarifiers gather fine suspended particles into clusters the filter can trap — good for silt, pollen, and dead algae. But a great deal of what dulls water and forms waterline scum is dissolved and emulsified organic waste: body oils, sunscreen, lotions, cosmetics. There's nothing for a clarifier to gather. Enzymes are biological catalysts that break those large organic molecules into smaller ones the filter can remove or that leave the water entirely.

The 24 to 48 hour circulation requirement is the part people shortcut. The product does the converting and breaking down; the filter does the removing. Every gallon has to physically pass through the media, and a typical residential pump takes 8 to 12 hours for a single turnover. The full window gives the pool several complete passes.

One boundary worth stating: Pool Juice Zero is not a sanitizer, algaecide, or shock. Removing phosphates makes algae far less likely to establish, but it does not kill algae that's already growing. A pool that's currently green needs shock and an algaecide first.

Pro Tip: The water will cloud after application, and that's the treatment working — don't reach for a clarifier. This is the most common support question on any phosphate remover, and the label states it plainly. The haze is dissolved phosphate converting into filterable solid, and on a pool that's been accumulating for a season or more, that's a substantial amount of new material appearing at once. It clears within 48 hours as the filter pulls it out. Adding a clarifier on top just loads the filter faster. What actually helps is running the pump continuously, watching the pressure gauge, and backwashing if pressure climbs 8 to 10 psi above normal — then backwashing again at the 48-hour mark as directed.

Dosage Reference

• One bottle per 20,000 gallons of swimming pool water
• Pools under 10,000 gallons: do not exceed 16 fl oz in one treatment
• No dilution required

Before You Start

1. Before application, make sure swimming pool equipment is working properly.
2. Backwash and rinse the filter according to the manufacturer's instructions. This matters more here than with most products — the filter is what removes the converted phosphate, so it needs capacity available.
3. Note your normal operating filter pressure so you have a baseline.
4. Confirm your pool's actual gallon capacity before measuring.
5. If the pool is green or has visible algae, shock and treat with an algaecide first, and let that work before applying this product.

Application

1. Apply Pool Juice Zero at a rate of one bottle per 20,000 gallons of swimming pool water, around the edges of your swimming pool. For swimming pools with less than 10,000 gallons, do not exceed 16 fl oz in one treatment.
2. Allow the pump and filter to run continuously for 24 to 48 hours. Swimming pool water may cloud upon application of this product but will clear within 48 hours.
3. Monitor filter pressure and backwash if it rises 8 to 10 psi above normal operating pressure.
4. After 48 hours, backwash and rinse the filter according to the manufacturer's instructions.
5. Retest phosphates to confirm the treatment worked, or to determine whether another application is needed.

After Treatment

• Once phosphates are in the acceptable range, switch to a weekly maintenance product to keep them there
• Retest phosphates periodically through the season, especially after heavy rain or runoff
• Confirm sanitizer and balance are back in range after the filter work

When to Use It

• A phosphate test reads well above the acceptable range
• Recurring algae blooms with no obvious cause despite adequate sanitizer
• At opening, after a winter of accumulated runoff and debris
• After heavy rain or irrigation runoff carrying lawn fertilizer
• Following an algae treatment, to remove the nutrients that fed the bloom
• On a salt pool where cell scaling is a recurring problem
• When waterline scum and dull water accompany the phosphate problem

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: Correct once, then maintain — don't use a corrective product as your routine. Pool Juice Zero is built to bring a high reading down fast, and it's the right tool for that job. But once phosphates are back in range, holding them there costs far less with a light weekly product than with repeated heavy treatments. Phosphates enter continuously from runoff, weather, and swimmers, so a pool treated once a month spends three weeks of every four rebuilding the reserve you paid to remove. Correct the problem, switch to a weekly routine, and you'll likely never need the corrective bottle again unless something unusual happens — a major runoff event, a long stretch of neglect, or a new fill.

• Mineral system pools — fully compatible

Filtration Systems

• Sand, cartridge, and DE filters — the filter is what physically removes the converted phosphate, so it must be clean and running continuously

Where Phosphates Come From

• Source water — some municipal supplies add phosphate as a corrosion inhibitor
• Ground runoff — rain and irrigation carrying lawn fertilizer into the pool
• Weather — storms, wind, and airborne debris
• Decaying leaves, grass clippings, and organic debris
• Swimmer waste, body oils, and cosmetics
• Phosphate-based sequestrants and metal-control products

Corrective Versus Maintenance

• Pool Juice Zero is the corrective product. Use it when phosphates have accumulated and you need levels down fast.
• A weekly maintenance product keeps phosphates from rebuilding once you've corrected, at a much lower cost per week — and it typically adds waterline protection and clarifying to the routine.
• The usual sequence is a corrective treatment first, then weekly maintenance to hold the line. Correcting repeatedly with a heavy product is a more expensive way to solve a problem that maintenance prevents.

What It Does Not Do

• Not a sanitizer. Provides no disinfection and maintains no residual.
• Not an algaecide. It removes the food source but will not kill existing algae. A visible bloom needs shock and an algaecide first.
• Not a substitute for water balance or filter maintenance.

Important Handling Cautions

• Never mix with other chemicals. Add products separately, allowing circulation between additions.
• Do not exceed 16 fl oz in one treatment in pools under 10,000 gallons.
• Expect filter pressure to rise during treatment.
