EHEIM KARBONFilter carbon for clear aquarium water – especially for new tank installationsEHEIM KARBON is particularly suitable for water purification during the set-up phase of the aquarium. In particular, chlorine from mains water and other chemical substances, which can get into the aquarium during installation, are safely taken up. EHEIM KARBON should be used for a short time (ca. 4 weeks) in the layering set-up after the mechanical (e.g. EHEIM MECH or MECHpro) and the biological filter media (e.g. EHEIM SUBSTRATpro) in the net bag provided.-Binds chlorine and other chemical substances-Use e.g. during set-up or after treatment with medications-Use for a short period (ca. 4 weeks)-Only suitable for fresh waterTip:Only use adsorptive filter media for a few weeks, as the harmful substances are only attached and can loosen after some time and be reintroduced into the water. At the very least they should be changed regularly. Normally adsorptive filtration is only necessary during aquarium set-up or after treatments with medications.mechanically:NoBiological:NoAbsorptive:YesChemical:NoNet bag:NoFreshwater:YesSea water:NoWidth:140 mmHeight:177 mmDepth:73 mm

For mechanical prefiltration of fine dirt particles Sera filter wool for the mechanical prefiltration consists of stable fibers that retain finer dirt particles for a longer time without sticking or collapsing. sera filter wool can be washed out several times. Suitable for all filters. We recommended sera siporax Professional for the biological filtration. sera siporax Professional is open pored and three dimensional - for lasting pollutant breakdown. Sera filter media must be rinsed under warm water before using it for the first time. Tip: When used in combination with sera phosvec･clear, sera filter wool makes it easier to remove the bound substances.

The fine and coarse filter pads are reusable many times over. To clean them simply rinse and squeeze out, so that the bacteria cultures are not completely destroyed. 

BOYU BIOCHEMICAL SPONGE FILTER This simple internal filter works with the power of any air pump connected to it by means of a flexible hose. It can also be used as a pre-filter for external filters or power heads. Sponge filters provide a suitable mechanical and biological filtration, according to the size of the filter and the bio load of the aquarium. They are cost-effective as they consume only a tiny amount of power to pump the air needed. Diameter: 7,5 cm Height: 9,3 cm Height incl. exhaust pipe: 19 cm exhaust pipe may be shortened by cutting)

EHEIM phosphate outChemically effective phosphate remover inhibits algae growth.EHEIM phosphateout is a special iron compound for chemical filtration. The iron binds the phosphate, removes it from the water cycle and gradually reduces the phosphate content in the aquarium. This primarily inhibits algae growth.When the phosphate content and thus the algae growth increases again, the filter medium is exhausted and must be replaced.EHEIM phosphateout is available as granulate for external filters and as a foam cartridge for internal filters. It is free of harmful substances and is suitable for fresh and sea water. Phosphate remover inhibits algae growthIron compound, free from pollutantsSuitable for fresh and sea waterSingle use (replace if phosphate content increases again)For external filters as granules, for internal filters as foam cartridgeChemical filter mediaDepending on the type, chemical filter media influence the pH value and water hardness (peat) – or reduce the phosphate content and inhibit algae growth (phosphateout).The pH value of tap water is usually between 7.3 and 7.8, which means it is slightly alkaline. However, most ornamental fish require acidic water - a pH value below 7.0. EHEIM PEAT pellets lower the pH value and reduce water hardness.Phosphates are mainly caused by organic contamination of the aquarium water (food residues, excrement, etc.) and are responsible for algae growth. EHEIM phosphateout binds the phosphate and removes it from the water cycle.

Fine and coarse filter pads for mechanical and biological filtration

For the prefiltration of coarse dirt particles sera biofibres for the biomechanical prefiltration effectively collect coarse dirt particles. Thus, you can protect the following filter media from coarse pollution and increase the biological efficacy of the filter. Suitable for fresh water, marine water and pond water filtration. sera biofibres also serve as an excellent spawning medium and as hiding place for fry. Furthermore, they are ideally suitable for transporting shrimps – they provide a foothold for the animals in transport bags and thus ensure they encounter less stress.

Bio Filteration Bioball 37mm OUTSTANDING FILTRATION! Each bio ball is covered in spines to dramatically increase the surface area of each ball to nearly 2 square feet providing space for a massive number of beneficial bacteria to colonize. These good bacteria break down harmful organic waste. You will receive approximately 300 1-1/2-inch bio balls in a mesh bag. Just rinse and use. TOUGH AND UNIQUE! Our bio balls’ spherical shape and precise spine placement permits them to pack tightly into any shape or filter type without losing surface area. Molded from high density plastic, these balls are lightweight but tough enough to keep their shape and will never degrade or wear out. Bio balls can be used loose or in the mesh bag with plastic zipper. TRUSTED! Our Bio balls are 100% polypropylene making them reliable biological filtration media for fresh and saltwater. They are manufactured for use in koi and water garden ponds, freshwater fish tanks, saltwater aquariums, aquaponics, fish hatcheries and much more. SUPERIOR TO LAVA ROCK: Over time, porous lava rock becomes clogged with d debris decreasing its surface area so that its ability to house and grow good beneficial bacteria plummets. Our bio balls’ uniquely spaced spines allow most debris to pass right through them. Lava rock has tiny pores which make it difficult to clean while bio balls in most applications never need cleaning. A bag of wet lava rock is many times heavier than our bio balls. EASY TO CLEAN - When organic waste builds up in the bioballs, they can be gently rinsed in dechlorinated wate to remove debris and refresh the bioballs. Use our FilterFIrst, dual density bonded filter pad, or water polishing pad to capture large particles before they can be trapped in the bioballs.

VERSA MAX 2 Sponge cartridges for AQUAEL filters made of carefully selected phenol-free sponge. They ensure efficient mechanical filtration of water, keeping impurities and suspensions visible to the naked eye.  At the same time, they are a substrate for nitrifying bacteria, thanks to which they also perform biological filtration. To ensure optimal performance of the inserts, it is recommended to replace them regularly and keep them only in "old" water taken during aquarium changes.

Fine and coarse filter pads for mechanical and biological filtrationThe porous material becomes evenly soaked with water and traps large and small dirt particles. After a short start-up period purification bacteria, which provide intensive biological decomposition of harmful substances, colonise the specially structured foam.The fine and coarse filter pads are reusable many times over. To clean them simply rinse and squeeze out, so that the bacteria cultures are not completely destroyed. -Porous material traps large and small dirt particles-Good colonisation conditions for bacteria cultures-Reusable several times over-To clean just rinse and squeeze outmechanically:YesBiological:NoAbsorptive:NoChemical:NoNet bag:NoFreshwater:YesSea water:YesWidth:180 mmHeight:180 mmDepth:70 mm
