The system can use any one of a myriad of different cartridges, all varying in quality ,performance and price.The 2 most popular are the melamine resin and the granular activated carbon. The melamine resin is best for dirt,rust,sediment and wriggler applications.It flows at an incredible 75lpm and is washable and reusable without flow rate drop or pump backpressure. Great for protecting hot water services,whiter whites and just cleaner.fresher water. The GAC or carbon filter,designed in this instance for great flow,is required in instances where smells,tates or odours occur. Where tannin is a problem,especially from decaying or rotting vegetation occuring within the tank,sometimes the melamine resin will remove it, if not severe,wheras the GAC will always remove it. Please note that the GAC should never beused without adequate prefiltration in front of it.The ideal scenario in this case for longer filter life,better flow rate and great results is a combination of both bfilters in line, one after each other.
