Finally (in Jan 2013) upgraded my cone skimmer with new high air flow (1400 L/h) water pump
Babble Blaster 3000.
Had to cut a new hole for the intake fitting as it would not fit in to the old one.
Skimmer is ridiculously powerful and very stable with this new pump.
Looking back there was no need to go with pump that big, as I had to take measures to reduce turbulence. BB2000 would have been enough.

As you can see compare to when skimmer was running on old OEM pump the skimmate now is denser and darker and also is stinks a lot more.
