Don't buy it
Foam cup for the protein skimmer arrived broken. Second rubber 3M stickers that go on magnets kept falling off as I repositioned the skimmer and the filter. Third the filter is design for up to 65 gal. My tank is 45 and the media that I put in to it ( recommended by experts) is to much for the power of the filter. At last I positioned both machines on the corners as the manual explains and even with power heads the water circulation between the units and the glass is very poor to almost none. Disappointed with German product for the first time in my life.
