This is the out flow from tank one into tank five. It is an inexpensive way to move water. Today we are purchasing a generator that will run the central air pump.
We use rotary blowers that last for years, but we do have a new one in storage. We have air lifts in every reef tank in our coral farm. As long as we can keep the air flowing these tanks are in no danger for at least 24 hours.
