Description
SpaGuard Phosphate Remover - 1 Pint
Reduce High Phosphates and Help Protect Spa Equipment
SpaGuard Phosphate Remover is a liquid spa and hot tub water treatment designed to quickly reduce high phosphate levels. Phosphates can enter spa water from fill water, body care products, detergents, leaves, debris, and other contaminants. When levels climb too high, phosphates can contribute to water quality issues and calcium phosphate scale buildup that may affect spa surfaces, heaters, plumbing, and equipment.
This 1-pint bottle is ideal for routine spa maintenance and targeted phosphate reduction. Use it weekly to help keep phosphate levels in range, or apply a higher treatment dose when phosphate levels reach 1,000 ppb or higher. SpaGuard Phosphate Remover is especially useful in saltwater spa systems, where controlling phosphate levels can help support better system performance and equipment protection.
SpaGuard Phosphate Remover may temporarily cloud the water, which is normal and indicates the product is working. For best results, follow treatment with SpaGuard Water Clarifier, run the filter, and clean or rinse the cartridge after treatment.

Product Details
Compatibility and Requirements
SpaGuard Phosphate Remover is intended for spas and hot tubs and can be used as part of a regular water care routine. It is especially recommended for saltwater spa systems, but retail sources also describe it as usable with most systems.
Before treatment, test phosphate levels using an appropriate phosphate test method. If phosphates are already low, routine weekly dosing may help keep them in range. If phosphate levels are 1,000 ppb or higher, use the higher treatment dose, then test again the following day.
Temporary cloudiness can occur after use. This is normal and indicates the product is binding phosphate so it can be removed by filtration. Follow immediately with SpaGuard Water Clarifier, run the filter, and clean or rinse the cartridge after treatment.
