Replacement needle wheel impeller set for Bubble Magus Skimmer NAC6A, NAC7 and any skimmers that use the atman ph2500 pump.
With the Needle Wheel, the skimmer will perform 20% more than the Meshwheel and it wont break like the meshwheel does. However for the first week or two, there will be some noise. The noise level should go away after it breaks in.
