Efficiently removes nitrates from marine and freshwater aquariums. 2 pcs - 3.75 x 3.75 x 1in Anaerobic-Blocks treat up to 1,000L/264 Gal
Maxspect Nano-Tech Anaerobic-Blocks efficiently remove nitrates from fresh and marine aquariums. This proprietary technology is specifically designed to stimulate the growth of anaerobic bacteria which completes the nitrification cycle essentially breaking down nitrates into the form of nitrogen gas. The Nano-Ceramic beads in the Anaerobic Blocks are specially treated to excel at establishing anaerobic heterotrophic bacteria which strives in anoxic environments. The porous structure is the ideal living condition and environment for bacterial colonies, and will not decompose or become brittle.Â

x1 - Anaerobic Denitrification Catalyst
Place directly in the sump, stack two Anaerobic Blocks on top of each other, and place a Denitrification Catalyst in between the blocks as illustrated to the left. The Denitrification Catalyst should be replaced every two months. The Anaerobic-Block should be cleaned or replaced every six months for optimal results. However, it is suggested to only clean or replace half of the Anaerobic-Block so that bacterial colonies remain and established themselves on the new or recently cleaned blocks. Â
