The integrated DC powered pump of the Coral Box D300+ Protein Skimmer significantly decreases its footprint. The base's diameter is 5 3/4 inches, or 6 1/2 inches with the gate valve included. The skimmer has a neck diameter of 2.5" and stands 19" tall. The cup's height is 4 3/4" and its diameter is 5.5". The drain on the skimmer cup contains a drain pipe and valve.
Each Coral Box protein skimmer comes with a Coral Box DCA skimmer pump that is completely controlled. A controller included inside the pump with 10 output modes lets you change the flow rate from 10% to 100%. With 1, 2, or 3 presses of the feed button, the three feed timers can be set for 10, 30, or 50 minutes, respectively. To stop the feed timer and restart the skimmer, press the button a fourth time.
