Groundbreaking filtration media at the right price. For Reef, Marine, Planted, and Fresh Water aquaria!

The PURA family of filtration media is formulated to reduce scum formation in fresh and marine aquaria.

All PURA products are formulated with Beta-GFH (Beta Ferric Oxide Hydroxide), the groundbreaking German made phosphate removing media that eliminates the primary nutrient of aquarium scum. PURA filtration products lead to a much cleaner and less labor-intensive aquarium, good for the animals, good for the hobbyist, good for customer retention.

Hydrated Beta-GFH is vastly superior to white colored Alumina based phosphate removers and greatly superior to numerous Alpha-Ferric Hydroxides sold in dry form.

PURA PhosLock removes 45% more phosphates than Alumina media, and 20% more than Alpha-Ferric Hydroxides. Unlike Alumina, PhosLock never leaches phosphates back to the aquarium. Unlike competing Alpha-Ferric Hydroxides, PhosLock never disintegrates and never turns soft and muddy in aquarium water. PhosLock comes fully activated right out of the jar. PhosLock does not need a specialized reactor and can be easily confined and implemented in a fine meshed media bag.
