I want to take out the oil film on water, this will impact CO2?

ordloh;40591 said:yeah that shouldn't be a problem. I turn my skimmer on at night to improve gas exchange and turn it off when the lights come on. by the way, are there any good quality skimmers out there? all the surface skimmers i get here are cheap and pretty crappy.

I really can't say why, but it didn't work for me, plus it's a surprising amount of tubing. It's a lot bigger then the pictures suggest.Brian20;40629 said:Hagen surface skimmer are good?

They must work. Again, (they really are bigger in person) I was not happy with the look of all the grey piping and I never could get the suction right. The little surface skimmer float thing never stayed at the surface were I wanted it. In my case the hose size was a little off from my Eheim and it never did fit properly. Yes, the duetto seams big. The truth is I found it to be more effective, versatile and thus less of an eyesore because of it.Biollante;40651 said:It looks like a number of commercial surface skimmer I have seen and a couple of diy as well.
