The powerhead also includes a venturi with an adjustable aeration valve and 8" of tubing to maximize oxygenation. Penguin's single moving part construction means no messy assembly, no oiling and virtually no maintenance. The epoxy sealed moisture-proof motor and electrical components ensure safe operation in both freshwater and saltwater aquariums. Size: 2" long x 4" wide x 3.75" high
