Polyplab Genesis Rock Power Rack FULL is the best tool for adding a massive amount of surface area for bacterial colonization without taking up too much space in your aquarium system.

The new Genesis Rock Power Rack organizer contains four (4) blocks of our Genesis Rock ceramic beads sintered together into a square block measuring 4 x 4 x 7/8 of an inch thick. This block provides over 1,000 square meters or up to 11,000 square feet of surface area.                                                                                                            

The Genesis Rock ‘bio-block’ is so manageable that it is easier than ever to tuck into many small spaces of your aquarium, including your all-in-one filter section, overflow boxes, and, of course, anywhere in your sump that has a respectable flow rate.

The Genesis Rock Power Rack organizer gets even simpler to use, clean, and set up in your system, minimizing your maintenance routine time and the overall look of your filtration area.  

On top of all, the Genesis Rock Power Rack organizer create the perfect conditions either your aerobic or anaerobic bacteria to colonize the Rock and grow. Easy to set, just add or remove the water flow deflectors included in this kit
