Dymax Bio Sphere is a highly porous media designed to be a substrate to bio-filtration, specially remove ammonia and nitrite(nitrification) and reduce nitrate(denitrification) for freshwater, marine and reef aquariums. This product cultivates nitrifying bacteria on its outer sphere and denitrifying bacteria in the inner, thus provide exceptional efficiency to eliminate toxic substrate and prevent algae growth.

The AquaClear 30 Power Filter features a unique multi-stage filtration system that provides complete mechanical, chemical and biological filtration for superior water quality. The Power Filter has a filtration volume that is up to 7 times larger than comparable filters. It also allows superior contact time with filter media. The filter preserves beneficial bacterial creating a stress-free environment for aquarium inhabitants and maintaining clear aquarium water. Its unique waterfall design enables filtered water to return to the tank silently, gently breaking the surface tension and creating beneficial oxygenation.

Filter Wool Is not only able to trap bacterial colonies but above all also acts as a filter material for catching coarse dirt and debris.

API® BIO-CHEM STARS biological media provides a home for growing massive colonies of nitrifying bacteria to establish and maintain a healthy aquatic ecosystem. The nitrifying bacteria convert harmful ammonia into nitrate. This is called the nitrogen cycle, and it occurs naturally in all underwater environments. Your fish will produce waste, which fuels the growth of the beneficial bacteria that will comprise your “biological filter”. These bacteria continue to grow as your aquarium ages – living on the top layers of the aquarium gravel, or in filter media such as API BIO-CHEM STARS biological media. Formed under a patented production process that creates a 50-70 micron internal pore network. This pore size is optimal for the growth of beneficial, nitrifying bacteria that remove toxic ammonia and nitrite. Space-age porous polymer allows for rapid transfer of oxygen and water which keeps bacterial colonies healthy and active. Due to their design, API BIO-CHEM STARS biological media achieve 4 times more surface area to colonize bacteria than ceramic rings. Size: 20pcs per pack. Rinse thoroughly to remove any dust. Place BIO-CHEM STARS biological media in the last compartment of your filter. BIO-CHEM STARS biological media will become colonized by bacteria within several weeks.

Eliminates toxic ammonia nitrite and nitrate.

Containing a superior blend of resins and activated carbon that removes aquarium pollutants – including colors, odors, heavy metals, and toxic gases – API® BIO-CHEM ZORB filtration media makes aquarium water crystal clear. Product also removes light blocking impurities for improved growth of corals in saltwater, and for plants in freshwater aquariums. 1 pack - size 6. Rinse pouch under tap water to remove the loose dust. Pouch does not need to rinse clear. Place pouch in path of water flow in the aquarium filter. Replace every 2 months, or sooner if aquarium is heavily stocked and/or colors or odors are detected.

CupriSorb is a powerful adsorbent of copper and heavy metals. CupriSorb will remove copper more rapidly and efficiently than carbon and is thus ideal for emergency copper removal. It extracts all types of copper, including chelated copper, and remains effective until it turns a deep blue-black colour. It may be regenerated repeatedly. If placed in continuous use, it will gradually extract even precipitated copper from the gravel/substrate bed as well. CupriSorb will allow maintenance of invertebrates in copper-treated tanks by removing copper leaching from substrates. CupriSorb is a powerful copper specific chelating resin. Competing products are not chelating products, but merely cation exchange resins. Such resins can remove copper from freshwater but are ineffective in saltwater. FEATURES: Powerful adsorbent of copper and heavy metals Copper specific chelating resin Removes all types of copper DIRECTIONS: Use 250 mL for every 600 L (150 US gallons) to remove up to 7,500 mg (12 ppm) of copper. Use in filter media bag such as The Bag. For best results, CupriSorb should be placed so as to maximize the flow of water through it. To remove undetectable substrate leaching copper keep CupriSorb in use for at least 2 weeks after copper tests report no copper. Use in a canister filter, chemical filtration module, box filter, or any high flow area of a trickle filter.

Black Alder Cones (Alnus glutinosa) harvested from European alders. This product is made by nature and supports plant growth, gently decreases the pH value and blocks harmful bacteria and fungi.

Key features: - For freshwater aquariums and ponds - Helps remove ammonia rapidly - Maintain pH value - Removes unpleasant odours

Has an absorbent effect which means harmful substances are broken down by aerobic and anaerobic bacteria who are given an exceptionally large area of colonisation (approx. 765m_) by the material. Nitrite and ammoniac are absorbed efficiently, nitrate and phosphate are broken down significantly and the biological balance is assisted.
