Automatic Makeup Water For Aquarium

Step 3 Fixture Holds Reservor In Correct Position

Tried just placing the water reservoir in an upright position but found the water would not flow out !  Believe it was due to surface tension in the hose.  Tried an number of hose positions etc  but nothing worked.  Found this approach was best.  Built a fixture from wood to position the reservoir such that the outlet is facing down at about a 20 degrees.  Kept the hose straight to the "tank hose holder" with no dips.  Worked great.  The water will stop at the fish tank water surface as air can not get back up into the reservoir to reduce the vacuum that is holding it from flowing out.
