SpaBoss No Phos (1L)

NO-PHOS is a naturally formulated water additive that removes phosphates from pool/spa water. The existence of phosphates in the water can encourage algae growth, as phosphates are nutrients for algae. No-Phos is not an algacide or algae stat and does not kill algae. Normal sanitizer levels will kill algae and No-Phos helps with the sanitizer efficiency. Refusal use of No-Phos will help prevent the existence of all types of algae.
