Ok, I'm slow
...I finally get the concept of the "siphon Break" using airline tubing from the return up to the water surface....I saw a tank today which used this technique and I finally see the point, that it will immediately break the siphon for you instead of continuing to back siphonl until the water level drains down to wherever a hole has been drilled. Yes I am going to do this.
