A marine water aquarium without a filter is inconceivable !
The marine water is polluted daily by remains of fish food, coral food and excrements of fish and corals. These partly microscopically small particles have to be removed from the water.
Either mechanically with a filter bag, skimmer or filter foam or chemically by filtering with activated carbon or phosphate adsorber.
This category offers the right filter technology for marine water aquariums. Here you will find skimmers for marine water aquariums, universal filters, zeolite filters, biopelle reactors, plankton filters, macroalgae filters, various filter bags, filter foam, etc.
Also various filter media or filter materials such as activated carbon, biopellets, filter foam, filter material ( phosphate adsorber ) to reduce the phosphate content and much more.
