Building a 1 acre pond. Someone has mentioned something about a trickle tube for the overflow spillway. To keep the water from swirling and allowing air access. Not using the entire volume of pipe for water. Curious if so where to purchase. Thanks

No idea, but I'll give your post a bump.

Is this the same thing as an anti-vortex plate or would serve the same purpose? I have seen them home-made, but I'm not sure where to buy such things.
