Need help with hang on overflow

[gaijin]

I have always had a problem with my hang overflow unit. The siphon
always gets an air bubble in it and eventually gets big enough that
the siphon is in danger of breaking and the water level in the tank
gets very high.

While tinkering around today, I noticed that if I remove the overflow
part of the box that sits inside the tank that the air bubble
dissapears and the water flow greatly increases. Anyone have any idea
what this means and does it give any hints as to a possible fix.

Does it mean that the overflow box is too small? I have used over
flows before and I just don't know why this one is giving me this
problem.

That's why built in overflows are so much better.
Remember that next time you are purchasing a tank.
So many stores push the overflow box because it's
easier for them to make a sale, and the customer is
none the wiser. In the mean time, here is a little
trick that I found to help. Cut you a piece of vinal
tubing that is narrow enough to easily slide through
the U tube. Cut that piece of vinal tubing 1 inch in
length.

Tie a piece of fishing line to it, and stick it into
the U tube. Then with the water flowing through the
U tube and down the overflow, adjust the position
of the 1 inch tube to a position that helps keep the
bubbles from becoming a problem.

Oops that should have said 1/2 inch, instead of 1 inch.

Thanks for that, I will give that a try. Do youhave any idea why the
bubble dissappears whe the box is removed from the tank?

I'm assuming that you are referring to the box that
is in the aquarium.

It's because the water level in the box is lower
than the water level in the aquarium, and when you
lower the box into the water, it has more pressure
to push the bubbles through. By increasing flow
rate, and/or decreasing U tube diameter, you
decrease the chance of bubbles staying in the U
tube. By the way, if you were to experimentally
remove the inside box, you would get more water flow
through the U tube, but as soon as the water in the
tank reached equilibrium, the water flow would be
back to where it was originally.

I see, yes that makes sense....
