It cleaned the surface of my tank in 2 HOURS and keeps it clean.
Just what I was looking for and all my parameters are just perfect.
And problems with extra connections just on the canisterfilter and perfect cleaner water.

Hmm... I would be very careful if I were you! Very high percentage of organic waste (proteins, lipids, nucleotides etc...) sediments on the substrate and/or adsorbs on highly porous solid phases (like LR), creating very thin layer. High water current disturbs such a layer and "redissolves" organic impurities. Subsequently, they are trapped on the air/water interface in skimmers. The active skimming surface of your water in the tank is nothing compared to the surface of millions micro bubbles that are created during skimming process. You may be lucky now, but it may happen you add one fish more and boom: ammonia/nitrite/nitrate spike and game over! You would not want that! As Matt suggested, proper maintenance and disturbance of water surface, by eg. circulation pump should be more than enough to get rid of unpleasant thin layer of organic impurities.
Hope this helps ! Cheerio!
surface suction extractor - GREAT
