Spa phos control

Product: In stock

Product Overview

This treatment can be used as a weekly treatment to eliminate phosphates or as needed to correct more severe problems. Phosphates feed on algae and promote their growth. They can be introduced into the water through rain, fertilizers, sunscreen, and other unexpected sources. This treatment is not affected by sanitizers and works in all pH conditions without changing the pH level.

Use one capful in a spa on a weekly basis to keep phosphate levels below 125 ppb.
1. Rinse cartridge.
2. Use 15 mL (three capfuls) per 1,000 L of water to reduce phosphate levels by 1,000 ppb (e.g.: if the phosphate level is at 1,000 ppb in a 1,500 L spa, use 23 mL (five capfuls)).
3. Disperse the product at the surface of water all around the spa, as wide as possible.
4. Run the pump continuously for 24 hours.
5. Rinse the spa cartridge regularly.
6. Recheck the phosphate levels after 48 hours. If necessary, redo the treatment.
NOTE: This treatment may cloud the water; this side effect is normal and will clear with filtration. To speed up the process, use a “natural” based clarifier in conjunction with this product. See your professional pool and spa dealer for more details.
