Laguna Biospheres provide large living area for beneficial bacteria to thrive. Placed in a pond filter, Biospheres efficiently reduce ammonia and nitrite to help maintain healthy pond water conditions and the overall well-being of pond fish and plants. Each Biosphere provides 158 square cm of usable surface area for the proliferation of beneficial bacteria. Biospheres can be used in almost any pond filter, making them more powerful and efficient.
