Safe-N-Clean - Basal 2910-020 Chemical Safe-N-Clean Spa Clarifier Gel Cubes - 2 Pack
This amazing spa clarifier is a highly soluble time-release, non-toxic and biodegradable gel. The gel increases the surface area of your filter and gathers together microscopic algae, bacteria, and other solids suspended in the water. Just place in your spa pump basket, turn on the pump, and it goes to work. Use monthly and your water will stay healthy, sparkling clean and clear. A normal pump run time of 8 hours can be reduced to 2-4 with the use of Safe-N-Clean Spa Clarifier. Best of all, Gel-caps are pre-measured, easy to apply, and fit in the palm of your hand! Each concentrated slow-dissolving gel-cap treats up to 1,000 gallons.
