Laguna biological Bio-Max is ideal for underwater filters. Bio-Max promotes, protects and encourages beneficial bacteria in pond water resulting in a clean, clear pond. The filter media has a large surface area and large number of perfectly sized pores to allow bacterial colonies to thrive which 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 BioMax rings held 6.9 grams of bacteria, over 400% more than a plastic ball biological media, which supported only 1.5 grams.
