Maxspect Denitrification Catalyst 5 Stk für Maxspect Anaerobic Block (M-AC5)

Stack 2 Nano-Tech Anaerobic-Block horizontally in the technical tank, placing the denitrification catalyst between the two blocks in the hollowed-out area.

For optimum efficiency, the Nano-Tech Anaerobic-Block should be cleaned or replaced every 6 months. However, when cleaning or replacing them, DO NOT change them all at once. Clean or replace only half of them so that there are enough bacterial colonies left to grow in the freshly cleaned or replaced Anaerobic-Block.

The denitrification catalyst should also be replaced every 6 months.

For freshwater and saltwater aquariums.
2 Blocks can treat up to 1000L / 264 Gal
