Natural Chemistry PHOSfree Phosphate Remover, 3 L Bottle | 15121NCM

Algae needs phosphates to grow — PHOSfree takes them off the menu. Poured into your skimmer, this Natural Chemistry formula works inside your filter to strip phosphates out of the water, cutting off the food supply algae depends on so your sanitizer can keep water clear with less effort.

• Removes phosphates — the nutrient that fuels algae growth
• Simple skimmer application — pour in, let your filter do the work
• Won't cloud your water when used as directed
• Works with every sanitizing system — chlorine, salt, and mineral systems alike
• 3 L bottle — enough for initial treatment plus season-long weekly maintenance for most pools

Pro tip: pair regular PHOSfree maintenance with proper sanitizer levels for water that stays clear all season — without emergency algae treatments.
