The TECO Flow Indicator is an important accessory for most aquarium system setups. Connect the Flow Indicator to any pipe or tubing that water flows through. The red fan in the middle will spin--a visual indication that water is presently flowing. The Flow Indicator can also be used to "join" tubes or pipes together.
Works on all chillers using 5/8" ID (inside diameter).
Compatible with TK500, TK1000, & TK2000 and HY500, HY1000, & HY2000 model chillers.
