Nano-Tech Anaerobic-Block (2 pcs)

Natural & Low-Maintenance Nitrate ReductionEfficiently removes nitrate from aquariumsDesigned to stimulate growth of anaerobic bacteriaNano-ceramic, porous structure that will not degrade over timeCan be used directly in sumpLasts approximately 6 monthsFor freshwater and marine aquariumsMaxspect Anaerobic-Blocks are desingned using proprietary technology to foster the growth of anaerobic heterotrophic bacteria which reduce nitrate into nitrogen gas, completing the Nitrogen Cycle through denitrification. Each block is comprised of proprietary Nano-Ceramic beads made to create a porous surface and anoxic interior perfectly suited for establishing colonies of Paracoccus denitrificans, various Pseudomonads, and more to aid in aquarium filtration.Recommended Use:Stack two Anaerobic-Blocks horizontally directly in sump, placing a Denitrification Catalyst between the two blocks. The Denitrification Catalyst should be replaced every 2 months, while the blocks themselves will need to be cleaned or replaced roughly every 6 months. Do not replace all of the blocks at the same time. Clean or replace half of the blocks so that sufficient bacterial colonies remain to re-establish themselves after each change.SpecificationsPackage Contents – 2 Anaerobic-Block piecesDimensions – 3 3/4″ x 3 3/4″ x 1″Surface Area per Block – 11,033 ft2Maintenance – Clean or replace every ~6 monthsTreats – 1,000L / 264 Gallons
