As a hot tub owner, you are undoubtedly looking for great ways to keep your water clean and pure.  One method for maintaining your water is to use the Thermoclear system.  With Thermoclear, you simply insert a special cartridge in the filter of your hot tub and then add Spa Activator 20 minutes before you use your hot tub.  When you use this system, your water won’t need any maintenance for up to four months at a time.  If your water is already experiencing problems, on the other hand, you can use Spa Activator to get things looking great once more.
