Automatic Makeup Water For Aquarium

Step 2 Fish Tank Water Outlet

A 3/8 inch plastic hose is used to get water from the reservoir to the the tank.  The water level will be determined by the outlet position of the hose so it must be held securely.  Made this one from some stainless sheet metal with Nylon screws to hold it to the tank and small stainless screws to hold small plastic pipe clamps that support the hose.  Inserted a small piece of ridged plastic pipe into the flexible hose so it could be clamped securely.  The Nylon screws at the bottom were cut to a length that kept the stainless sheet metal properly positioned in the tank.
