Two full sized Patented Downdraft™ Technology skimming towers.
Provides a tremendous surface area in a small space for very effective air-water mixing and greater pump efficiency. Think of it as two skimmers build into one body.
Extra large user adjustable flow range puts you in control of your tanks water quality by allowing you to adjust the skimmer's throughput to suit your tank inhabitants needs.
Automatic air flow regulation, needs no adjustments. One great feature of all downdraft skimmers that is not apparent until a skimmer has been owned a while.
All skimmers using air flow adjustments, beckett and spray injection types come to mind, are subject to a constantly changing air flow adjustment. They do not hold a setting due to salt "creep" buildup in their air intake. This is not a problem for Downdraft skimmers. |
