Aquasparkle Spa Clarity Cubes are ideal for restoring water clarity & sparkle to your spa / hot tub and swim spa. Aquasparkle gel cubes are designed to remove small particles from your filter and assist with the restoring of your hot tub back to sparkling clear water. The gel cubes are designed to add clarity to your spa water when your tub is looking cloudy and tired looking. Ideally used with a cartridge filter on most spas, hot tubs, above ground pools, and swim spas. A build-up of cloudy water is caused by non-filterable waste particles that the filter does not pick up due to being too small.
