Bio Balls can easily be used instead of heavy lava rocks in a biological pond waterfall filter. With our selection of Bio Balls, you can replace your heavy bags of lava rocks with a much lighter option! This makes getting into the filter pads in a waterfall filter very easy.
Unlike lava rocks, Bio Balls never need to be rinsed off! While lava rocks clog with dirt and debris, reducing the active surface area for good bacteria to grow on, Bio Balls are engineered to prevent this from happening and allow for 44 square feet of surface area!
Replacing the lava rock in your BioFalls filter with Bio Balls will increase the biological filter’s capacity and improve your filter system! When using Bio Balls, you should also notice a slight increase in water flow from your BioFalls filter because they have less resistance than lava rocks.2 cubic feet will fit into one black mesh media bag not included.
