The aqua one phos pad is a tightly woven chemical filter pad which absorbs phosphate from your aquarium water.  High phosphate levels within an aquarium is one of the major food sources from algae.  Phosphate builds up over time as a result of too much or poor quality fish food, lack of regular water changes and decaying plant or animal matter.

• Suitable for fresh and saltwater aquariums
