The MAV AquaDoc Spa Clarifier is designed to quickly clear cloudy water in hot tubs by clustering tiny dirt particles so the filter can easily remove them.

Using it is simple—just add the recommended amount while the jets or blower are running, and run the filtration system until the water clears. Many users appreciate how fast it works and find it easy to use regularly.
