I would like to announce that the Alpha 200, 250, and 300 is receiving a nozzle change. The original design implemented the manual change out of different length nozzles for different air draws. The new design gets passed over from the Bubble King Deluxe and Super Marin series, and one that the Alpha 170 has already received, which is a tunable venturi. This will allow users to adjust the air draw by turning the nozzle inward (less air flow) or outward (more air flow) based upon the demands of the system and the performance desired by the hobbyist.
Well.. I only have one nozzle, so will be one of the first in line to get one of these....
