Thanks to its unique ceramic structure, Bio-Max promotes, protects and encourages beneficial bacteria in pond water, resulting in a clean, clear, and sludge-free pond.

Bio-Max has the largest surface area and number of pores perfectly sized to allow bacterial colonies to thrive, creating a bacterial sanctuary that maintains a biological balance in pond water.

Beneficial bacteria living in micro-tunnels and micro-cavities naturally eliminate ammonia and nitrite, which are toxic compounds that originate from pond inhabitants, decomposing organic matter, and run-off from surrounding terrain. 

Tests performed in overloaded pond conditions with live fish showed that Bio-Max rings held 6.9 grams of bacteria, over 400% more than a plastic ball biological media, which supported only 1.5 grams.
