The double cone Super Marine line of Bubble King skimmers from Royal Exclusiv are the newes top end skimmers from the German skimmer and pump manufacturer. If a well designed cone protein skimmer can reduce turbulence and increase the skimming capacity of a protein skimmer, why not do double cone with one at the neck and at the diffuser plate? The jury is still out on whether the double cone design has any real advantage over just a cylinder and a cone, but either way this video of the BK Super Marine 250 in action is interesting to watch.
