Overflow without drilling

[Slaapkousie]

Need advice on a suitable solution for an overflow in a Juwel tank.

Return pump from sump does 4800lph

What overflow box / method will handle this return flow?

Note that I do not suggest this method at all, it is far safer to drill a hole. I have tried the above and it failed at least once a week.

Thanks man. Know of that technique aswell. Just want to me sure overflow can handle the 4800lph that gets pushes into the tank.


So looking for options.

I decided to go the ghost overflow route based on bean animal's design
