Blue Circle Phosphate Filter Pad

Blue Circle Phosphate Pad is a 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. Phospahte pads should be used as a preventative or treatment, not a cure for prolonged phosphate concentrations in your aquarium.
