Marinepure PLATE 20x20x2.5cm 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.

Marinepure BLOCK 20x20x8cm Ammonia, Nitrite & Nitrate Removal Primarily designed to provide deep anaerobic zones for de-nitrification in passive or low flow systems. Live rock substitute Use in Aquarium sumps

EHEIM filter cartridge (2 pcs.) p. PowerLine XL Mechanical and biological filtration cartridges. Dirt particles are retained by the porous foam. At the same time, the material offers a large colonization surface for cleaning bacteria. Shortly after start-up, the cartridges provide not only mechanical cleaning, but also biological degradation of...
