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.
