    Hi all

    Decided to get my A into G and start building my DIY skimmer....:)

    Here's some specs to tease you:p

    Chamber Dia = 300mm.
    Chamber height = 700mm.

    Holding about 50ltrs I could always use it as a nano tank :biggrin:

    Watch this space!!! :yeahdude:

    Wouldn't have a clue on it rating, personally I think most ratings are a thumb suck?

    But with the right pumps etc I would guestimate about 2000-4000ltrs?

    Will post a pic just now.

    A skimmer that size needs a lot of air. Air driven or venturi?

    Did you make the top? that idea of putting a cylindrical weight on top and heating sounds like it would work:) the top of that cone is too skinny though IMO

    i built a diy skimmer a couple of years ago and made my own needle wheel impeller(cash flow at the time was really tight) the problem was that when i turned skimmer off i had to jiggle it to get it going again!
    i was wondering would it work to have two venturis one after the other in series on one line with one pump pushing the water through. would it work? would it improve bubble to water ratio?

    I would think that with all the back pressure of that size skimmer you'd need a hell of a strong pump and then to ensure a good fllow of bubbles is another mission. Maybe the use of a few smaller same rating pumps. The only crux with that is you may have too many variables to control (height of pumps and air inflow), my DIY was a serious fiddle to get all in balance. Gimme a shout if you want some input.

    Tagging along on this build :thumbup:

    Not sure I'm with you Pads, this will be an external based skimmer, what back pressure is there?
