Evolve filters have been designed with the aim of giving the koi keeper for the first time the design and components within their filter that most closely match their requirements and pocket. The Evolve filters range is based on the vastly superior horizontal flow principal. The Evolve filters range are also available as pump or gravity fed versions. Once you have decided on the basic filter that matches your pond size you can decide whether for the mechanical component you wish to stick with the more standard labour intensive but cheaper brushes, in which case you can have up to three brush cartridges or go all in and opt for the self cleaning drum filter. You can of course update your brushes at a later date for a Drum filter as and when funds are available. For the biological stage you have the option of using heavily aerated Japanese matting cartridges, moving bed technology utilising genuine K1 or both options in one filter chamber. To explain the options you have new improved 15mm genuine Japanese matting cartridges or high quality stainless steel baskets with lids to house your moving bed media such as the K1 supplied.  On the larger Evolve 4000 and 6000 filters you can mix the media in each media bay. For instance on the Evolve 6000 you have four options, you can have all three bays containing matting cartridges, or one three bay stainless basket with moving bed K1 or one bay of matting with a two bay stainless basket with K1 or two matting cartridges and the single K1 basket. The baskets are also ideal for housing whatever media or supplements you like. For maintenance purposes the drum and all the media can be removed from the filter in less than 60 seconds
