Chitosan Clarifier for Spas


Clarifies Cloudy Spa Water

SeaKlear pioneered the use of chitosan in pool and spa water clarification over 30 years ago. The original Chitosan Clarifier for Spas uses high-quality chitosan to deliver superior water clarity. It contains recycled shells from the seafood industry that would have otherwise ended up in landfills. This tried and true technology doesn’t interfere with the performance of other spa products. It even works with high sanitizer levels and can be used at the same time as shocking your spa. Chitosan Clarifier for Spas works to improve filter performance while keeping spa water clean, crystal clear and sparkling.

This is the product that started it all. Our flagship clarifier is made from recycled crab shells, making it a reliable, environmentally friendly solution for cloudy water problems.
