Product Overview

SeaKlear PhosKlear 4000 is a powerful phosphate remover designed to reduce phosphate levels that can feed algae and contribute to dull, hard-to-manage pool water. By targeting phosphates at the source, PhosKlear 4000 helps your sanitizer work more efficiently and supports consistently clear, inviting water.

Ideal For

• Pools struggling with recurring algae despite proper chlorine levels

• Reducing phosphate buildup from leaves, pollen, rain, runoff, and swimmer waste

• Improving overall water clarity and filtration performance

• Ongoing preventative maintenance for pools prone to algae pressure

Key Features

• High-strength phosphate remover (PhosKlear 4000)

• Helps reduce nutrients that algae depend on

• Supports clearer water and easier pool maintenance

• Works with most pool types and filter systems

• 32 oz bottle for convenient dosing and storage

Benefits

• Helps prevent algae problems: Less phosphate means less fuel for algae growth.

• Boosts water clarity: Helps your filter capture and remove phosphate-related debris.

• Easier maintenance: When phosphates are under control, sanitizer demand may feel more manageable.

• Great for trouble pools: Ideal when water won’t stay clear or algae keeps returning.

How to Use

1. Test phosphates (recommended) to determine treatment needs.

2. Ensure circulation is running and water chemistry is reasonably balanced.

3. Add the product per label directions—typically poured slowly into the skimmer or in front of a return jet.

4. Allow the filter to run continuously as directed; water may cloud temporarily as phosphates are captured.

5. Clean/backwash filter as needed after treatment.

6. Retest phosphates and repeat if necessary.

Temporary cloudiness is normal—this indicates phosphates are being bound for removal by your filter.

Customer-Facing Q&A

Q: What do phosphates do in pool water?
A: Phosphates act as a nutrient source for algae. High phosphate levels can make algae blooms more likely and can contribute to water that’s harder to keep clear.

Q: Will this kill algae?
A: PhosKlear 4000 isn’t an algaecide—it removes phosphates (algae “food”). If you currently have algae, treat the algae first with a proper sanitizer/shock routine, then reduce phosphates to help prevent it from coming back.

Q: Why did my pool turn cloudy after adding it?
A: Cloudiness is common and usually means the product is binding with phosphates so your filter can remove them. Run the filter and clean/backwash as needed.

Q: How often should I use phosphate remover?
A: It depends on your pool environment. Pools with heavy debris, frequent rain/runoff, or lots of use may need periodic phosphate maintenance. Testing phosphates is the best way to determine timing.

Q: Is it safe for all pool types?
A: It’s generally compatible with most pools and equipment, but always follow label directions—especially if you have a specific surface type or cartridge/DE/sand filtration.
