The spherical shape allows for high bulk density, meaning the full volume can be utilized in the filter (filter baskets or units). Additionally, the improved surface of the spheres ensures intensive stability of the important bacteria for water purification. A dense bacterial lawn is formed.  \nThe large number of bacteria also reduces nitrite peak loads and extends the filter material's lifespan.  \nEHEIM SUBSTRATpro is suitable for both freshwater and saltwater, washable, and can be reused multiple times.  \n\nEnhanced biological filtration medium made of fused quartz  \nHigh bulk density due to spherical shape (balls)  \nVery dense bacterial colonization  \nLonger service life  \nBetter degradation of nitrite pollutants  \nCan be reused multiple times (wash carefully for cleaning)  \nSuitable for freshwater and saltwater  \n\nBiological filtration media  \nThe main task of biological filter material is to provide the best conditions for bacterial cultures to grow, so a bacterial lawn develops after a short period. The bacteria feed on all types of dirt particles and convert substances that are critical for the aquarium.  \nAfter initial cleaning with mechanical filter media (such as EHEIM MECH or MECHpro), biological filtration is the most important. It ensures clear, healthy water and stable water values. That's why we invested a lot of research into developing biological filter media.  \n\nTip:  \nNever clean or replace the biological filter material completely at once (and never excessively). Bacterial cultures should not be completely destroyed, otherwise recolonization will be delayed. Filter baskets in external filters and filter units in Aquaball and Biopower internal filters are ideal for partial cleaning.  \n\nMechanically: No  \nBiologically: Yes  \nAbsorptive: No  \nChemically: No  \nNet bag: No  \nFreshwater: Yes  \nSaltwater: Yes  \nWidth: 140 mm  \nHeight: 177 mm  \nDepth: 73 mm","brand":"EHEIM","offers":[{"title":"Default Title","offer_id":43594433790045,"sku":"EH2510051","price":42.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0568\/0106\/7101\/files\/5BEH2510051_5D_20EHEIM_20SUBSTRATpro_20720g_20_E2_89_88_201l_20filter_20media.png?v=1780585235","url":"https:\/\/shopivet.com\/en-us\/products\/eheim-substratpro-720g-1l-filter-media-102299","provider":"Shopivet.com","version":"1.0","type":"link"}
