T5000 Shorty Compact Protein Skimmer 29" Ocean Runner 3700 with Modified Needle Wheel Impeller up to 400g tanks 14" x 14" Footprint 150gph Flow req. From the successful Turboflotor 5000 series we have developed these powerful protein skimmers for cabinet installation. They close the gap between the Turboflotor 1.000 multi Ð for aquaria up to 250 gallons and the Turboflotor 5000 baby for aquaria 500 gallons. The Shorties are manufactured in 2 sizes to fit into most aquarium cabinets. Like the larger models, they are supplied with a venturi pump and our patented needle wheel and foam cup. The water supply to the skimmer requires a second pump with a capacity of minimum 500 gph. The skimmer may also be directly connected to the overflow of the aquarium. In this case it is recommended that a bypass be installed to control the water flow to the skimmer, especially if powerful return pumps are used.
