    Skimmer for block construction

    What skimmer would you use for block construction? I'm looking for wide mouth and do not need the UV lights in the skimmer.

    I'd also like a 4" throat.

    Any reason you're looking for the "wide-mouth" versions? Although they are wider up-front w/a larger faceplate, they (i should say most major brands that i've seen) still funnel down to either a 6" or 8.5" floating weir door like such ...

    Will you be utilizing the cylindrical baskets inside this skimmer or will it gravity feed to a remote "leaf basket"/pre-filter?

    I take it due to the 4" request, you'll be gravity-feeding to a tank/pre-filter?

    Most of the styles can be easily modified to 4" by cutting off the bottoms & utilizing a 6" x 4" rubber coupler similar to this Waterway FloPro II I modified:

    Certain wide-mouth skimmers "work better" (think easier to install) when building a pond with concrete cinder blocks.

    Something like the wide-mouth on Birdman's site (scroll down to bottom).

    Thanks for the information.

    Yes, it will be gravity fed to a Cetus so I want 4".

    Ric, I like this skimmer with the built in overflow but it's in the UK.

    I would seriously suggest you rethink the use of a no-niche skimmer. They are out in the pond where fish can hit them....or you may hit them with a net. Also they do not handle much water.

    Consider using either a pool skimmer (8" or 16") or a skimmer made for ponds. Using the pool skimmer lets you run larger pipe sizes to the pump for greater flow rates.

    On our semiraised pond I used a Savio 16" skimmer and put a 3" bulkhead fitting in the back floor. It gravity feeds a pump in the filter pit. If I could redo our pond, I would use two skimmers located in adjacent corners as debris tends to go to corners due the currents caused by air domes on the bottom drains.
    Koi keeping is not a belief system; it is applied science with a touch of artistry.
