    With the new professionel 4+ series, EHEIM once again sets high standards in aquarium filter technology. Many of the details and useful functions have been taken over from the previous filter model, the professionel 3. The most striking feature of the new professionel 4+ external filter is the emergency button "Xtender". This button makes it possible to have a little more time until the next cleaning of the external filter is carried out. Who of us aquarists isn’t familiar with this problem? Always when we have the least time the water throughput is low and the filter is blocked calling for an immediate cleaning. Using the emergency button "Xtender" you will gain a few more days without any adverse effect on the biological filtration capacity. The gradually adjustable Xtender button makes the water pass partly around the microfilter inside the filter system so that the water throughput is restored and the aquarium filter goes on working as usual. The new EHEIM professionel 4+ and its installation fittings come in fashionable anthracite colour. Apart from that, the EHEIM professionel 4+ retains lots of useful details known from its predecessor including the integrated suction aid for the filter start, the integrated stop valves, the large-volume pre-cleaner, the security hose adapter, and the Easy-Clean function. The high-class ceramic shafts and bearings ensure a very silent operation of the external filter for many years. The EHEIM professionel 4+ is definitely the best external aquarium filter currently on the market. All the extensive experience of the inventor of the aquarium filter is built into this model: uncompromising quality, high-quality materials and workmanship, useful and sophisticated functions – this is what the label "Made in Germany" stands for.

    A very good filter.

    Though I don't like the sound of the pump when it starts, it makes some terrible screeching sound.

    Other than that, it has a very good flow and comfortable access to filter media.

    So I am very glad I purchased it.

    I have a 140L tank and want a filter capable of dealing with fish solids and to give it more turbulence!Do you think this filter be ok or too big.I have a eheim internal bio power 200 at present and with only feeding once a day-the filter does not seem to be filtering small solid waste from tetras.Any advice would be welcomed have had fish for 30 years, but need to purchase one that is on top of the filtration.

    Aquaristikshop.com:  This filter would be a very good choice for for your tank. The EHEIM professionel 4+ has a large prefilter and its pump is very powerful. You can control the flow rate by using the tap on the pressure side.
