Aqua One Phos Pad

The Aqua One PhosPad is a tightly woven chemical filter pad which absorbs phosphate from your aquarium water. High phosphate levels within an aquarium is one major food source for algae. Phosphate builds up overtime as a result of overfeeding or poor quality fish food, lack of regular water changes and decaying plant matter. PhosPad is not a substitute for good aquarium practices. PhosPad should be used as a preventative or treatment, not a cure for prolonged phosphate concentrations in your aquarium.

It is essential you replace the PhosPad after 4-6 weeks. The microscopic pores in the pad can fill up and release all the waste previously collected, back into your aquarium.
