Internal filter for aquaria in three stages

Filters for completely Submersible Aquarium with a three-stage filtering and water flow adjustable which allows you to recircular the water in three different ways.

This revolutionary filter is available in four versions depending on the size of your aquarium. They can be used in tanks of freshwater or saltwater, tortugueras or terrariums. All them less model U1, have three stages of filtering to ensure a water crystal clear and free of impurities:

  • Stage 1: foam Foamex, which acts as a cernidor and retains large particles (U1, U2, U3, U4)
  • Stage 2: cartridge of polyester and active carbon that retains small impurities, improves the quality of the water and removes particles that cause bad odor or stained the water (U2, U3, U4)
  • Stage 3: Biomax for an optimal biological filtration. It offers an excellent substrate for the colonization of beneficial bacteria to remove ammonia and nitrites of the water of the Aquarium (U2, U3, U4)
Three components filter

These units are ideal as a complement to other filters or only Purifier for the Aquarium. It is very versatile and easy to install; You can place both in the vertical as a horizontal position, ideal for shallow terrariums or aquariums with large decorative elements. They are fully submersible and work in very quiet and efficient manner. You can put them anywhere in the Aquarium, even on irregular sites that do not use tubes or hoses, only the power cord. Different programmable in three modes output allows you to create streams of water in different directions, facilitating the movement of water even in the most difficult corners. Higher mode produces a stream that provides maximum movement and a great proportion of oxygen. Core drilling generated a flow in the form of curtain which forms a broad stream and the lower mode creates a flow of water at the bottom of the Aquarium, ideal to get organic waste that are deposited there and delete them with the filter.

Three programmable outputs

The filter can be installed in two different ways; with an arm hanging it from the edge of the aquarium or by the holder with suction cups to adhere to any part of the glass. Both systems are included with the product. The components of the filter can be changed very easily without having to remove the unit from the water through the Flip Top system, which allows you to open it from above, remove the cartridge and load the new. Although the filter has been designed so that you can change parties without having to remove it, you can do so simply by withdrawing its support.
