This spa sanitization system kit includes a key pad and bromicharge. With its waterproof enclosure and sturdy design, the IN.CLEAR is one of the most efficient water sanitation systems in the spa and hot tub industry today. The IN.CLEAR system requires very little maintenance and can be easily installed in new or existing spas in horizontal or vertical orientation. The IN.CLEAR is an environmentally friendly system that generates and releases bromine into the spa water with the primary purpose of controlling and rapidly destroying any microbiological contaminants such as waterborne bacteria, algae, body chemicals, organic matter given off by spa bathers and other organisms known to be linked to recreational water illnesses. Due to its superior disinfection properties, the new IN.CLEAR system eliminates the need to add extra chemicals in the water to destroy pollutants and get great results.
