GARF'S AIRLIFT MAKING LESSON = bubbles and sun
LEROY@GARF.ORG



This is the finished airlift. We will use several sizes in the new system. This size will be used in the 300 gallon round tanks to create the water flow around the tanks. The airlifts are buried in the gravel, and they create water flow through the gravel. This filters the water and keeps the gravel from getting too low in oxygen.
