    Pinwheel.

    There's also that mesh which people use called enkamt or something like that.

    Most newer high end skimmers use the pinwheel. It depends on what pump you want to use. Some pumps where the pinwheel is used makes allot of noise and also gets stuck. I had problems with the Oceanrunner and Octopus pumps. Mesh can work but than again also problems with it getting stuck. What pump do you want to use it on and sometimes it might be just a watse of you bucks.

    Its going to make a hell of allot of noise those pinwheels, or meshing it. Stick to the original impeller. If you have time and bucks than get those pinwheel or Enkarmat and diy, good luck.

    do spiderweb conversion and your needlewheel will whip ass. if unsure borrow my otp 3000 and the two different impellers and test to see which would be better for you.[​IMG]
    ps if you put two 5mm ceramic washers on front of impeller if pin wheel it prevents contact with cover and no noise results

    Any pump as long as it doesnt apply too much pressure. thepurpose is just to prevent front of impeller touching housing. look at the inside of housing to see if impeller is leaving marks on it. if you see marks put washer in if not noise has other source.

    thanks Mandarinman

    I have noticed when the airline hose is pinched, it quietens down, but the skimmer suffers and doesnt skim. I kinda seems like the pump is cavitating.
