Blue Ram Posted June 28, 2006 Report Share Posted June 28, 2006 I recently set up a 50 gal freshwater tank with an eheim professional series canister filter. This is the first tank that I have used a canister filter on. I have the output directed approx. 2 inches below the water level. There has consistently been a skim on the surface of the water. First, can someone pls explain why this happens. I have an eheim protein skimmer attachment (which I acquired from another eheim model (2213) which I connected to the filter (this is just an attachment to the output). However, I have no manual on how this is supposed to work. It does not appear to completely remove the skim so I'm thinking maybe it is not adjusted properly. Is anyone using this equipment and can explain how to properly set it up? Quote Link to comment Share on other sites More sharing options...
Blue Ram Posted June 28, 2006 Author Report Share Posted June 28, 2006 I looked on Eheim's website - this accessory is actually called a "surface skimmer". Here's the link to what it looks like http://www.eheim.com/skimmer.htm Quote Link to comment Share on other sites More sharing options...
Cichlid88 Posted June 28, 2006 Report Share Posted June 28, 2006 It should be attached to the filter input not the output, i've used them in the past they seem to work well. Cheers... :beer: Quote Link to comment Share on other sites More sharing options...
Blue Ram Posted June 28, 2006 Author Report Share Posted June 28, 2006 Sorry, I meant the input. Are there any adjustments that need to be made so that it does a better job on the surface?? Quote Link to comment Share on other sites More sharing options...
