After a short start-up period purification bacteria, which provide intensive biological decomposition of harmful substances, colonise the specially structured foam.The fine and coarse filter pads are reusable many times over. To clean them simply rinse and squeeze out, so that the bacteria cultures are not completely destroyed.Porous material traps large and small dirt particlesGood colonisation conditions for bacteria culturesReusable several times overTo clean just rinse and squeeze outEHEIM MECHPrefilter material made from hollow ceramic rings for trapping large dirt particlesDirectly after entering the filtration cycle, water is swirled through the hollow ceramic rings. Larger dirt particles thus sink to the bottom. The treated prefiltered water then continues its way through the other filter layers.

The spherical shape gives a high bulk density. Thus the whole of the volume in the filter (filter baskets or modules) can be utilised. Also the optimum surface of the beads provides intensive colonisation of the important purification bacteria.Due to the high number of bacteria, peak nitrite loads are more easily reduced and the maintenance intervals of the filter material are longer.EHEIM SUBSTRATpro is suitable for fresh and marine water, is washable and can be reused.Optimised bio-filter medium made from sintered glassHigh bulk density due to spherical shape (beads)Very dense colonisation of bacteriaLonger intervals between cleaning Better reduction of nitrite loadsReusable (rinse carefully to clean)Suitable for fresh and marine watermechanically:YesBiological:YesAbsorptive:NoChemical:NoNet bag:NoFreshwater:YesSea water:YesWidth:175 mmHeight:337 mmDepth:269 mm
Aquael Fan Filter-Internal Filter[Size - Mini Plus]
Aquael Fan Filter-Internal Filter[Size ... 105.00 AED
The internal filter FAN is intended for cleaning and aerating the water in aquariums. Thanks to the specially selected sponge sitting on a perforated panel, it is particularly insensitive to soiling and does not require frequent cleaning. The protective plastic container holds back coarse dirt, which ensures efficient filtering of the water in the aquarium tank for a longer period of time. The AQUAEL FAN internal filter is easy to install and uncomplicated to operate. The specially designed chamber for the filter media prevents water from running out of the filter into the aquarium tank during the water change that has to be carried out at certain intervals or when the filter is removed from the tank, e.g. to wash out the sponge. The sealed rotor chamber ensures powerful, quiet operation with relatively low power consumption. In addition, the model variant of the AQUAEL FAN MIKRO internal filter can also be used in very shallow water with a depth of 2 centimetres, which means that it has proven itself excellently even in the smallest water terrariums. The option of regulating the flow of the FAN internal filter without having to put your hands in the water is very convenient. The dome with the ergonomic toggle handle can also be above the water level. The direction of the water outlet can be regulated in the range of 75 °. Product More Details  High efficacy   Fan filter has been equipped with solutions that ensure its efficiency and convenience. The design of the filter chamber prevents the unit’s water from pouring into the aquarium when removing the filter for cleaning and when changing the water in the tank. The plastic, locally perforated housing effectively traps larger contaminants as an initial filtration stage. The sponge placed inside the filter is responsible for the thorough water purification. Easy installation   The FAN filter is distinguished by its ease of installation and operation. Thanks to the adjustable hanger, the filter can be adapted to various aquarium glass thickness. Also a hose with an aeration valve can be attached to the hanger. The holder is equipped with four strong suction cups to securely fix the filter to the glass surface. High efficiency  The specially designed rotor chamber ensures not only unobtrusive operation, but also high device efficiency with minimal power consumption. It is worth noting that the FAN filter models consume between 4 and 12 watts. With this range of energy consumption, the monthly operating cost remains relatively low, which contributes to the economic management of the aquarium (see table at bottom of page).  Innovative solution  The option to adjust the output of the filter without having to dip your hands in the water is a unique and practical feature rarely found in similar devices. It is possible due to a dome with an ergonomic knob located on top of the filter, which can be placed above the water surface. This innovative solution allows the user to conveniently control the performance of the filter without direct contact with the aquarium water.   2 in 1: Filtration and aeration   Adjustment of the water outlet direction is possible within a range of 75° and can be controlled to the right and left. The FAN also has an aeration function. These feature make this small filter a versatile aquarium tool that can be easily adapted to individual needs.   Operating in very shallow water   The FAN MIKRO model can operate in very shallow water – as low as 2 cm deep – making it ideal for even the smallest aquaterraria.
