Mech Duo Cartridge

The BioLife Mech Duo-Density Polyester / Carbon Cartridge is the third and final step in mechanically scrubbing the passing water flow. The Duo Density polyester pad removes any fine solid wastes that escapes Stage 1 and 2. Following the final step in mechanical filtration, the carbon granules within adsorb liquefied wastes, medications or dyes into the huge internal carbon matrix. The efficient combination of  micro and macro pores adsorbs all sizes of liquefied wastes and gaseous impurities in the water stream before they can reach the "Dry" Chamber

Maintenance:

Thwe BioLife Stage 3 Duo-Density Polyester / Carbon Cartridges should be changed every two weeks to ensure water flow to the biological filter is pure. 

Pull old cartridge from the slot, discard and insert a new one into the empty slot. Ensure the arrows are facing down.

Bio Hex-Nodes

BioLife Stage 5

"Wet / Dry" Filtration System Media

The Bio-Life Hex-Nodes may be used either in a "dry" chamber or submersed in a water flow. They provide ideal surface attachment points for the beneficial bacteria to grow and thrive. Used in the lowest biological chamber of the BioLife Filtration System, they provide the finishing biological polishing of the water before it is exhausted into the aquarium.

Hex-Nodes require almost no maintenance. If there is any build up of deposits on the pieces, simply rinse the Hex-Nodes in aquarium water to ensure the bacterial populations are retained as solid wastes are washed away. Normal tap water supplies include Chlorine and Chloramine in the water that will kill most of the beneficial colonies of bacteria and should be carefully avoided when rinsing any biological media.

If desired, change half the Hex-Nodes 6 monthly. It takes time for an adequate population of bacteria to grow to a strength where they can remove all the ammonia and nitrite produced by the aquarium. When changing Hex-Nodes that have been previously initiated, do not change any other media at the same time. bacteria already in the filter and media will rapidly seed the Hex-Nodes

A-280 BioLife Stage 4 Bio Core

The BioLife Ceramic Filter Core provides the perfect place for beneficial bacteria to colonize and thrive.

The core should be removed and washed in aquarium water when clogged.

One half of the core should be replaced every 6 months
