Review on Aqua-Tech Power Aquarium Filter for 30-60 Gallon Tanks (ML90740-00) - Optimize Your Search! by Christine Pochmara

This small filter is very good value for money. Has worked for 3 months with no problems. The filtering works great. I also like that it can be disassembled for cleaning. There are a few downsides. First, it's a little difficult to get started. You must fill the suction tube with water before it moves. If you disassemble the filter you will also see the o-ring that starts to leak on the old filters. (Bought this to replace a 2 year old filter that was starting to leak.)
