Selling bioball used for biological filters for filtering pool water, aquariums, waste water etc., Bio ball is a water filter media that is very needed in biological filtration systems. Maybe for many lay people who do not understand what a biological filtration system is. Biological filtration system is a filtration system that works using microarganism / bacteria that work simultaneously because of its basic nature. The types of bacteria used are various types according to the purpose of the filtration system itself. For example to remove Ammonia will be different from the filtration used in filters that aim to remove fat or others. As we discussed above that bio ball in this case does not function as a "filter", so in fact this bio ball functions as a "media / place" for the life of microarganism itself. So the bio ball is not as a "filter" but as a medium where bacteria live, working or more precisely helping us to become "clean - clean", so that more "clean - clean" results will be cleaner.
