Precise porous structure - Provides a large number of beneficial bacterial strains such as nitrifying bacteria to improve biochemical filtration and stabilise water quality.
Convex and concave design - allows an even distribution of filter water flow, promotes rapid oxidation, reduces organic matter and is better suited for the cultivation of bacteria. Can be used in various filters and filter water tanks.
Good water circulation - fast water purification, good filtration performance, dense and even filter cotton fibres, effective filtering of fine impurities, high water permeability, no water accumulation, can maintain good water circulation.
Efficiency - Used in the filter system of the fish tank for secondary filtering, reduces bacteria in the water quickly, circulates filter waste and cleans the water.
Lightweight - Larger surface area and better filtration than filters with the same weight.
