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

Biological filter mat is made from high quality material which is helpful for developing nitrobacteria,with thick filaments and hard texture,so its good as middle-laying filter material. Healthy koi need clean water! There fore both mechanical and biological filtration is needed to obtain a natural balance in the koi pond. Biological filtration removes toxic ammoniac and nitrites by meansof bacteria. The righer filter medium gives a large specific surface area for the bacteria to attach to and simultaneously allows sufficient flow of water through the filter without clogging. -good water resistance,light resistance,excellent water and air permeability,flame resistance - washable ,recyclable many times - durable -size: 200x100x3.8cm
