Since Warner Marine’s first cone protein skimmer was announced last fall, a lot of changes have happened to the American made skoner besides the name. For starters, the Warner Marine cone protein skimmer was first launched as the K1 but it was later renamed the K2 to make room for an upcoming K1 cone protein skimmer which will have some mass-produced qualities. The K2 has also received a number of changes which are more physical in nature. The diffuser plate now has reduced number of diffuser plate holes which is thought to work better with the vertical bubble technology (VBT) of the skimmer which draws some of the skimmed water down through the center of the diffuser plate. The cup is now removable via a CNC machine threaded fitting instead of a cam-lock/bayonet fitting from before. Furthermore, instead of having the hand screw tightened fitting which formerly held the pump firmly to the body, looks like Jon may have read our post about the usefulness of silicone for quieting water pumps because the Sicce psk-1 is now mated to the skimmer body with a thin piece of black silicone. Last but not least, the needle wheel has now become retooled to have much thinner pins which should allow the Sicce to have less resistance, higher RPM’s and hopefully producing much reduced bubble sizes. If reducing turbulence is really the name of the game, then we have big hopes for the K2 and it’s VBT style diffuser plate which draws “used” water through the center and down the middle of the bubble plate. We’ll be keeping our lateral lines close to the ground for feedback on the final iteration of the K2 and we look forward to hearing more about the real K1 and forthcoming K3 cone protein skimmers. As usual, full gallery after the break.
