How Does It Work?
The porous ceramic structure provides an extensive habitat for beneficial bacteria involved in biological filtration.
By adjusting water flow through the rack, aquarists can influence the conditions surrounding the media, supporting different bacterial communities.
This can help strengthen the aquarium's biological filtration as the media becomes established.
Installation & Use
Position the rack in a suitable filtration compartment with consistent water circulation. Arrange the supplied deflectors according to the desired flow configuration.
Allow time for beneficial bacteria to colonise the media. Biological filtration develops progressively and should be monitored using appropriate aquarium water tests.
Why Choose Genesis Rock Power Rack?
An excellent choice for reef keepers looking to increase biological filtration surface area while keeping their sump or filtration chamber tidy and accessible.
Polyplab Genesis Rock – serious biological filtration in a compact, organised system.
