    Water treatment is an essential part of keeping a clean, safe, beautiful pool or spa. So, while you can stock your supply closet with chemicals like chlorine, bromine, and calcium increasers, your pool or spa may have more specific needs that these products don’t treat. When that day comes, turn to one of the most trusted brands for pool and spa maintenance: United Chemical.

    Treatments for All Seasons

    External factors such as the weather can have a big impact on the quality of your water. To combat this, United Chemical offers specific treatments for all seasons. Spring Treat kills the algae that may have grown over months of disuse while Winter Treat fights of stains and discoloration. There are even special solutions for the well-worn areas in your pool and spot treatments for unsightly stains.
