Product Overview

Natural Chemistry PHOSfree Phosphate Remover is a powerful phosphate-reducing pool treatment designed to help keep pool water clear, clean, and easier to maintain. PHOSfree uses lanthanum-based technology that works through the pool filter to bind and remove phosphates from the water.

Phosphates are a common nutrient source for algae. By lowering phosphate levels, PHOSfree helps reduce algae-supporting conditions and can improve overall sanitizer efficiency as part of a regular pool maintenance program.

Customer-Facing Q&A

Q: What does Natural Chemistry PHOSfree do?
A: PHOSfree helps remove phosphates from pool water. Lower phosphate levels can help reduce algae-supporting nutrients and make pool water easier to maintain.

Q: Does PHOSfree kill algae?
A: No. PHOSfree is not an algaecide. It removes phosphates, which are a food source that can contribute to algae growth. Existing algae should be treated separately with the proper sanitizer or algae treatment.

Q: Can this be used in saltwater pools?
A: Yes. PHOSfree is compatible with saltwater and chlorine pools when used according to the label directions.

Q: Will PHOSfree cloud the pool water?
A: PHOSfree is designed to work through the filter without clouding pool water when used properly. Always follow dosage and filtration instructions.

Q: Where do I add PHOSfree?
A: PHOSfree is typically added through the skimmer so it can work in the filter. Always follow the product label directions before use.

Q: Is this for weekly maintenance?
A: This 2-liter PHOSfree bottle is commonly used to lower phosphate levels before starting a weekly maintenance program. For ongoing phosphate control, customers may also use a weekly maintenance phosphate product as needed.
