Each Genesis Rock can support up to 1300 Litres of the aquarium water in a lightly stocked aquarium or 300 Litres for aquariums with a heavy bio load.
Lightly rinse each rock with RO water or some aquarium water before use to remove any dust caused by abrasion in transit.
Place the Genesis Rocks in a container, filling it with some aquarium water, and add PolypLab Genesis bacteria based on the size of the aquarium you are adding the rocks to. Allow for your Genesis Rocks to stand at least 12 hours, and then place them inside your aquarium and discard the water. If you are not using any bacterial supplement, you can place rock directly in the aquarium after rinsing but it will take longer for the beneficial bacterial colonies to establish. Avoid placing the rocks against a vibrating surface such as a return pump.
We recommend that the blocks are positioned after some form of particulate filter such as filter socks, floss or a ClariSea filter unit as detritus and debris can block the pores of the rock reducing the efficiency over time.
Optimised for Aerobic Bacteria Growth to Remove Nitrite and Ammonia
To use the Genesis Rocks to create more aerobic bacteria growth, place the Rocks in an area of high water flow. It is also possible to place the rocks above water level and allow water to run through them but care must be taken to avoid splashing and that water will not flow out of the aquarium. If this method is used a flow rate of up to 150 litres per hour should be used for each rock.
Optimised for Anaerobic Bacteria Growth to Remove Nitrate and Phosphate
Install the Genesis Rocks in an area of low flow to encourage a reduced oxygen environment. This can be a low flow area in your sump, refugium or hidden in your aquascape.
Optimised for General Performance and Growth of Aerobic & Anaerobic Bacteria
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.
