Frequently Asked Questions

Q: What do phosphates do in pool water?
A: Phosphates are nutrients that feed algae growth. By removing them, you help prevent algae blooms before they start.

Q: Will this affect my sanitizer levels?
A: No — removing phosphates supports sanitizer performance by reducing the organic load in the water.

Q: Can I use this with salt systems?
A: Yes, PhosFIGHT+™ is compatible with saltwater pools and all standard pool sanitizers.

Q: How do I know if I have high phosphate levels?
A: Bring a sample of your pool water to your local Poolife™ dealer for a free phosphate test.

Q: Can I use PhosFIGHT+™ after treating my pool for algae?
A: Yes. It’s an excellent follow-up to algae treatment because it removes leftover phosphates that could trigger future blooms.

Q: Will the water cloud after adding this product?
A: A slight, temporary cloudiness is normal as phosphates bind and are filtered out. This clears quickly with proper circulation and filtration.

Q: Is it okay to use this product year-round?
A: Yes. Weekly use, even outside of swim season, helps maintain low phosphate levels and prevents algae from gaining a foothold.

Q: Do I still need to use an algaecide with PhosFIGHT+™?
A: Not always. When phosphate levels are well-controlled, algae struggle to grow. However, in high-risk conditions, pairing with an algaecide can provide added protection.
