Looking for a DIY overflow box idea?

[Yates273]

Thinking about plumbing a 10 gallon tank in to add more macro algae. I plan on tapping off of my manifold for water and drilling a hole in 10 gallon tank to have it drain back into sump via gravity. Anyone have any ideas how I can make a small overflow box for the 10 gallon or does anyone have access to a 3d printer to make a small one just to keep the macro from clogging the hole?
One other idea would it be better to plumb the supply lines to the bottom of the 10 gallon this way there is flow underneath the algae and have it flow back into sump from top. Or just run the hose into the top of the tank TYIA

Just drill a bulk head for return, set to the level you want...if you absolutely want an overflow...I would get a 4-6" diameter piece of PVc and cut in half.glue it to a corner with your bulkhead for return.

I've been trying to do something similar for weeks. Haven't found much in terms of making it so its quiet other than an overflow box. But i really don't wanna spend the money on something so small

You can just drill a hole for return. The flow will be minimum so not much noise at all.

The problem is in the drilling. I have drilled many tanks but have failed to drill a 10g. Once I succeeded but the glass cracked when tightening the bulkhead. A standard 20g is much easier if you have the space.

I guess I got lucky. Bulkhead in now I have to finish my weir. Using 1/4 pvc board. I ended up using a 5 gallon tank right now 10 gallon didn’t fit where I needed it to be. Disregard bucket I will be making a stand just needed bucket for measurements.

Here’s the weir just need to silicone in now

Fingers crossed it works. All done just need to let silicone dry to put water in tank and test.
