Don't bother. It is not high quality. It is always getting air in the motor and it will stop working. Harder than hell to prime. Way harder than a Fluval 304 and at times those can be hard to prime. It is just a pain. I hate it and am frustrated with it. I am no novice aquarist. My experience is not common, but for me I will never buy another Eheim product. All of the pumps, heaters and filters I buy from this company usually end up breaking, running loud or not working properly. I would highly recommend using either Hydor or Fluval. No matter what any, so called experienced hobbyist says, Hydor and Fluval are way more reliable and of higher grade construction. Everything about this filter is cheap.
