    you will probably find the multi bay wonít filter that quick
    I have a 12000 kk multibay running a 15000 superfish though 2 inch pipe pump fed and I've had to blank the over flow off in the multibay and running it just to say boarder line . But I have bypass the uv till I get it fixed hoping the uv will cause enough restriction to flow perfectly

    oase aquamax eco 11500
    Oase aquamax 10000
    Oase Aquarius 4000E
    And a couple of other small pump but not sure on make or lph
    I would like to try and use the pumps I have rather than spending more money I was thinking the 11500 on the multi bay And the 10000 on the skimmer

    I have an aquaforte DJ vario which is good a lot us jebao pumps which meant to be the same.
    they are a good price and you can adjust the speed so turn them up-down to suit your pond and save money in the winter when less flow is needed.

    i had a few aqua Max’s good pumps still have one as a spare, the 10000 may be a bit on the big size for the skimmer, perhaps someone could confirm this (that’s why I was thinking the variable).
    i ran a 5500 aqua max on my old skimmer.

    Thanks I do have the 4000 but don't know if that's too small. I do have plenty of ball valves that I can use to controll the flow of the 10000 if needed

    I'd use either the 11500 or the 10000 on the bd and 4000 on the skimmer then, see how it gets on. Even at 14000lph you are turning the pond over once an hour. That's plenty isn't it?

    That will be very dependant on a lot of external factors, the quoted 14000lph is ideal conditions with no pipe and no head of water, you will probably only see 10000lph when you take into account all the pipe/bends/efficiency/age/head of water etc, etc

    So if I use the 11500 on the BD and the 10000 on the skimmer. I can use the ball valves to control the flow on the skimmer if needed. So with loss of head pressure ect even if I was down to 15000 that should be good. I think

    i would go 10000 after multibay,which im guessing is a cloverleaf from your drawing,and 4000 on skimmer,skimmers are there to just clean the surface so you dont need massive pumps,and multibays work better at a slower flow,as for bio you could convert the multi to static and fluid k1,lots did this to the multis before drums came out,you could add a shower after your skimmer but have the return to an underwater pipe so no noise,,,,,andi

    Thank you Andi.
    I'm not entirely sure what make of the multi bay is. Just know it's got a central vortex and 4 bays surrounding the vortex. I have got my eye on another 2 bay filter that I was going to buy to add after the multi bay And convert that to a static and moving bed.

    So would it be ok to have an under water return coming from a bakki ? I just didn't know if there would be enough pressure to push the water through

    Thanks again
