Aquarium decanter

Internal decanters are ideal for creating a highly efficient filtration system at the expense of the usable volume of the aquarium. They are made of plastic and must be glued to one of the internal surfaces of the aquarium with special aquarium silicone glue. Internal decanters should be equipped with a compact and efficient pump (2 to 3 times the volume in freshwater), filtration foam, and filter floss to be operational.
