    has anyone used a surface skimmer to increase dissolved oxygen in a tank? If yes, please share your experiences.

    My tank size is 48in(l)x18in(w)x28in(h).

    thank you

    I Like Surface Skimmers

    Hi,

    I really like surface skimmers, I like the results.

    The ability to have glass smooth surface while keeping the water well oxygenated.

    The lack of surface film is also very useful for the gas exchange and also helps keep your lighting levels consistent day to day.

    I am also a fan of surface skimmers.

    If you can drill a couple of holes in the back there are nice options available.

    Surface film

    It comes from different sources. It can be dust, it can be proteins and such from food, and it can come from fish as well. I'm not sure that plants directly produce it.

    Case in point, in my heavily planted biocube if I don't clean the overflow I'll get a thin film of stuff over the top but it's not a heavy film. On my discus tanks I don't have lots of plants in there and I feed heavily and can have a thick film on the top which I remove daily. If I'm careless with the water change and stress them too much they'll shed their slime coat which floats to the surface adding to said film. An overflow would at least sweep the surface clean but I'll still have all that "stuff" in the water to deal with one way or the other. Marine tanks, or high pH and hardness freshwater, then have the option of foam fractionation to strip that out, but it's not really an option for my tanks at the moment. The stuff on the top of the water when I've used the palm sander can be ridiculous....

    Slice The Surface

    Hi,

    One of the best articles on surface skimmers http://reefkeeping.com/issues/2003-04/gt/index.php also has a couple of calculators for figuring hole and drain sizes. It is oriented toward reef keepers. ;)

    A place to buy hole saws. http://www.glass-holes.com/Glass-Hole-Cutters_c7.htm I saw an ad somewhere for a set that includes some sort of holder to make it easier to start and stabilize the saw.

    I really like the over flow skimming real thin 'slice' off the surface. :cool:

    I agree with S, I do not think there is one source of surface film, I have seen film that really was serious polymerization, actually have seen a couple, I thought I might be able to pull thread.

    That's one of my favorite pages to quote when talking about skimmers! You didn't snag that from one of my posts did you? LOL

    Coast to coast is one of the best skimming methods out there and you can take it to the extreme with the zero edge aquariums as well.

    Hi S,

    Of course!:D

    Actually it has been a favorite of mine for many years, I love being able to 'slice' the top layer of water a sixteenth of an inch!:cool:

    I also love smart people that figure it all out and let dumb guys like me 'figure' things so nicely. :eek:

    The word skimmer was mentioned only twice in that reefkeeping article and I cannot find a calculator relating to skimmers.? :(

    Skimmer, Overflow Box, Sump, Return

    Hi,

    I think I sent the second part of a three-part article, at the bottom of the page you will see links for parts I & III. Part III, http://reefkeeping.com/issues/2003-07/gt/index.php, has the calculators. I think reading and understanding all three part is a good idea.;)

    In reef keeping lingo, skimming has a slightly different meaning, though the process is the same on the aquarium end. The water is ‘skimmed’ into an ‘overflow’, usually ‘box’ then into a ‘sump’. :)
