Serenity Bio-Filter Medium
Serenity Bio FIlter Features silent operation and has an excellent filtering effect while oxygenating the water. The specially developed foam materials supports the colonisation of bacteria, allowing for mechanical filtration in addition to biological filtration, which will break down harmful waste, ammonia and nitrate material, resulting in a cleaner living environment for your fish. They are particularly useful for a breeding filter, or as a secondary filter.
Suits tanks up to 150 litres.
