SpaBoss No Phos is a naturally formulated hot tub water additive that removes phosphates from spa water. The existence of phosphates in the water can encourage algae growth, as pho sphates are nutrients for algae. No-Phos is not an algaecide or algaestat and does not kill algae. Normal sanitizer levels will kill algae and No-Phos helps with the sanitizer efficiency. Regular use of No Phos will help prevent the existence of all types of algae. Show more
