Egg crate for weir overflow screen?

[dowsetts101]

I'm trying to work out the best approach for the "screen" on the top of my weir overflow in my new build. My weir is 10mm glass and finishes probably 10mm lower than my desired DT water level.

I plan on putting a screen on the top of the weir, to stop the livestock taking a whitewater rapid ride, and was originally thinking of a short acrylic strip with teeth sawed into it. Something like in this picture.

Then I thought of whether that egg crate material would serve a similar purpose. I would then extend the egg crate higher into my hood.

Thoughts? Maybe the grid size on the egg crate would be too big? I figured that someone has probably thought of this before...so keen to hear your thoughts.

I used gutter guard on my modified megaflows. It's small enough to block most fish and very cheap.

I hadn't even thought about gutter guard...that's even easier to lay my hands on than egg crate....especially with Bunnings 2 minutes down the road...thanks for that.

Buy a piece of acrylic from lowes or home depot. Ask them.to cut to fit your overflow then paint it in black.
Have done it so many times. they come out very nice once you paint it

You just can buy the overflow combs, not sure for where you are but my bet is it ain't that hard to find and it's cleaner look, almost a PRO look.

I ended up getting these from an Australian supplier...looking forward to installing them.

Thanks for the suggestion
