    I don't see why they can't make an impeller that does both, Push water with the blades & on the outer end have a needle wheel attached to break the air coming in.

    Or compensate with a stronger pump

    maybe i'm not following you exactly but both skimmers/pumps (BK and Deltec) employ needlewheels.

    I don't think anyone expected the Eheim to push as much air/water as the Red Dragon, but wheather that is a benefit or not is yet to be seen.

    OuinLA,

    It's simple, stick a normal impeller designed for that BK pump and I'll bet that you'll push more flow and pull in more air, but that doesn't mean it'll be a better skimmer pump with a normal impeller since the normal impeller won't break up the bubbles nearly as well as the needlewheels and that is what really counts because of the ratio between bubble surface area to bubble volume.

    Think about it, if needlewheels could move water as well as impellers designed for flow, you'd think that people would have moved onto that long before skimmers came around.

    Peace,
    John H.

    Dave, glad to hear that your system is getting back on track. Losing 900 pieces of SPS is no joke. It must have been a very sad weekend for you. Regards.

    Well the rains have finally started here - They say the first round is going to be 5 days.

    I know for you folks North of me, that is no big deal.

    I have tented the system, to try to keep the salinity issues in check. Have to see how it does.

    Tomorrow I will try to move the tents to give a better view of the skimmers running.

    My bad rufio. I understand the principle of needlwheels vs standard very well. I must have fallen asleep at the wheel for a second. I didn't realize you were commenting on my observation of the non needlewheel pump. i had forgotten that i had posted that. Sorry for the confusion

    Fkadir, thanks for the thoughts, but it's Dave (o2manyfish) that lost all the corals recently. nonetheless, i'm sure he still appreciated the statement

    The rain is causing trouble with the electrical run to all the skimmers. So until things dry out which skimmers and running and when, will be entirely determined by the location of the puddles

    As long as progress exceeds expenditures I can't complain.
