Cleaning your hot tub filters improves their efficiency and helps maintain sparkling water to do this use our filter and cartridge cleaner and soak your filter cartridges over night.  Certain water conditions and additions like cosmetics, soaps and body fats, if allowed to build up in water will create foaming. The simple addition of Relax Spa No-Foam will eliminate unwanted foam from spa water surfaces.  To restore the sparkle to dull water use our spa clarifier.  To prevent both staining and scaling it is a good idea to add a Stain and Scale Inhibitor.
