Polyplab Genesis Rock Power Rack - Empty

The Polyplab Genesis Rock Power Rack is an organizer that holds Genesis Rock bio-blocks, giving you a large amount of surface area for beneficial bacterial colonization without taking up much space in your aquarium system. This version is the empty rack, supplied without blocks.

Each rack holds up to four Genesis Rock blocks. Every block is made of ceramic beads sintered together into a square measuring 4 x 4 x 7/8 of an inch thick. The page states that each block provides over 1,000 square meters, or up to 11,000 square feet, of surface area.

The blocks are compact and easy to handle, so they can be tucked into many small spaces. Good spots include an all-in-one filter section, overflow boxes, and anywhere in your sump with a respectable flow rate.

The rack makes the blocks simpler to set up and clean. That helps cut maintenance time and keeps your filtration area looking tidy. It also creates conditions for both aerobic and anaerobic bacteria to colonize the rock.

It suits reef and marine aquarium keepers who want to boost biological filtration in a small footprint.
