VERSAMAX is an external hang-on filter designed for the filtration and aeration of water in regular-sized and nano-aquariums. Thanks to its high throughput capacity, the filter guarantees intensive filtration of aquarium water, while requiring very little space. The filter is very quiet and easy to use. VERSAMAX filters can be used in water tanks with the capacity of 50 to 300 liters. Each package includes a filter lid, a flow-through unit, and a container for filter media with a sponge cartridge. The VERSAMAX filter is completely watertight, because the entire container is made of one piece. Hang the filter on an aquarium wall so that the suction tube is inside the tank, whereas the body of the pump - on the outside. At the start-up, fill the filter container with water and then plug the connection cable into the mains. Shortly after the activation, a properly assembled filter will suck the air out of the suction system and start pumping water from the aquarium. The pumping capacity can be adjusted within a wide range by means of a dial located on the top of the flow-through unit. The pump draws water from the lower part of the water tank, next the water flows through the filter cartridges, and finally it is released back into the aquarium. The filtration baskets are designed to facilitate cartridge replacement. Filter throughput can be adjusted using the dial located on the top of the flow-through unit. The angle of inclination of the filter is also adjustable. The standard set of cartridges for the VERSAMAX filter includes a sponge cartridge made of special phenol-free sponge. It constitutes a particularly favourable substrate for the growth of bacterial cultures employed to remove organic impurities from the water. In this way, effective mechanical filtration is supplemented with excellent biological filtration. Filter cartridges can be freely combined or replaced with other filter media for biological or chemical filtration. For example, you can combine cartridges for biological filtration with a sponge for mechanical filtration. Make sure that individual media are arranged in equal layers in both parts of the filter baskets. In addition to a VERSAMAX filter, you can use a MULTI UV-C steriliser. For 20-100L tank use.
