Cavity Pro" has a larger surface area than the conventional "Cavity," and its filtration capacity has been greatly increased.
A filter medium that replicates the natural filtration cycle that occurs in the environment. This filter medium utilizes the "channel phenomenon," offering good water permeability and high filtration capability, making it the perfect filter medium.
This product is Cavity Pro, the highest-rated filtering material according to my evaluation as a resident of Japan.
Features
1.As water flows through randomly formed creases, debris adheres inside them, reducing clogging.
2.Equipped with both biological and physical filtration capabilities, eliminating the need for multiple types of filter media; just Cavity alone completes the filtration process.
3.Made of plastic, it does not adversely affect water quality.
4.Even when washed during routine maintenance, it does not produce powder or degrade like other filter media.
5.Very light and sinks in water (approximately 105g per liter).
*Note: At first use, air may be trapped in the creases causing it to float, but it will sink once stirred.
6.Less frequent maintenance.
Precautions
Without water flow, bacteria will not settle.
When starting up, it may take 1 to 2 weeks for bacteria to settle.
Use according to various filter sizes.

Manufacturer's Description
The purification mechanism of this product applies fluid dynamics and cavity flow analysis. It utilizes the phenomenon where debris accumulates in riverbed depressions.
Debris in the water settles at different rates depending on its size. Thus, when particles enter the product's creases, which simulate riverbed depressions, debris with slower settling rates is re-released while debris with faster settling rates accumulates within the cavities (creases).
These depressions, possessing optimal aerobic and anaerobic zones, allow bacteria and protozoa to thrive, enabling simultaneous physical and biological filtration. Moreover, the design almost completely prevents clogging, ensuring stable performance.
