MarinePure is the perfect place for beneficial bacteria to flourish in order to remove harmful fish wastes. It will eliminate ammonia and lower nitrates.

MarinePure's bio-media is the most technically advanced bio-media available today.

Features Thin Bio-Film Technology™

MarinePure is inert and will not harm aquarium inhabitants.

• Combination of vast surface area and open/interconnected pores allow a thin bio-film to develop.
• This thin film allows bacteria to flourish because necessary nutrients are immediately available.
• With the open pores, old dead bio-film is easily flushed from the media and will not plug the media.
• Water flows through the media, not around as with other denser medias, thus utilizing the most surface area for beneficial bacterial growth.

Designed for Ammonia and Nitrite Removal under high flow. Deep pore structure will allow development of low oxygen zones, which will help with control of nitrates.

Perfect for the creative hobbyist as it can be easily shaped.

Use in sumps, between baffles, shape to fit in tight/custom places.
