The Bubble King 180 Kone Skimmer from Royal Exclusiv is an evolution of the Alpha Kone skimmers with a more curvaceous body. The hourglass shape of the bubble king is exceptionally attractive, giving just enough clearance for protein skimmed water to pass around the fluted diffuser plate. Also different in the BK180 Kone is a threaded venturi inlet that will allow you to fine tune the amount of air and water going into the BK Red Dragon mini with utmost precision with a twist of the inlet. Also new in this design is a standpipe that is integrated with the body, leading to a more robust construction and a really cool appearance. Finally, the neck of the skimmer head is a threaded pressure fitting that is easily removed for complete access for cleaning this prized wine glass shaped cone protein skimmer.
