square feet of space per black for beneficial aquarium bacteria to form, these
blocks providing a tremendous amount of filtration power and significantly
reduce phosphates, nitrates, and other dissolved organic compounds. The Genesis
Rock can be used in fresh or saltwater aquariums and can be used under your
sand or rock substrate, in your refugium, or simply hidden in your aquascape.

Increased Beneficial Bacteria Colonies

Zero Leach Technology - 100% Fired Ceramics

Directions:

Each Genesis Rock can support up to 350 gallons of
the aquarium, our kit includes 700 gallons worth of coverage in two rocks.
Heavier bio load tanks such as predator tanks for example should increase the
coverage suggested above. Rinse material well with purified water, but
preferably aquarium water. Our rock is specifically designed for zero leaching
so we have very little dust, but we recommend washing just to be sure. 

Place Genesis Rock in a plastic
container, filling it with aquarium water, and then adding your favourite
bacterial product. Add your bacteria to the container based on the size of the
aquarium you are adding the rocks. Allow for your Genesis Rocks to stand at
least 12 hours, and then place them inside your aquarium. If you are not using
any bacterial supplement, you can place rock directly in the aquarium after
rinsing. You can discard the soaked water to ensure no microscopic
dust gets moved to your aquarium. Using more blocks than the capacity
recommended above is ok and will increase your filtration power. However, we do
not recommend exceeding 500% of the capacities listed above. 

Aerobic
- Optimized for Nitrite, Ammonia Removal

To use the Genesis Rocks to create aerobic
bacteria, place the Rocks above water level over your refugium, overflow, or
suspended in your system. Run tank water over the rock and allow the overflow
to run into your water column. Do not run your entire system flow over the
blocks, only around 40 gallons per hour estimated.

Anaerobic
- Optimized for Nitrate Removal

Install the Genesis Rocks in a very low flow area,
deprived of as much oxygen as possible. This can be a low flow area in your
sump or refugium, under your sand, or hidden in your aquascape. 

Aerobic
& Anaerobic - Optimized for general performance

Install the Genesis Rocks in a medium flow area of
your tank, sump, refugium, or other portion of your system which has a medium
flow of water. This will allow the outside of your Genesis Rocks to propagate
Aerobic bacteria while the inner portions of your Genesis Rocks generate
Anaerobic bacteria. 

*Be sure not to place the Genesis block in any area
where it might rub against other equipment and cause damage to the block such
as a vibrating protein skimmer as an example. *
