Fluval Evo 13.5

[milliesmillie]

Hello,
On my Fluval Evo 13.5, there is this hole in the back to help filtration if the water level gets too low, only issue is I get crabs stuck in the all time which increase pressure on the pump and the tank starts to fill above my safety line it overflowed a little this korning due to this.
Is there anyway to plug this?

Lots of people just stick some purple expoy ( IE the stuff for coral fragging)...or ask a friend to do a 3D printed plug

This is what I used, less than $5 with shipping.

I used that same plug and it made a huge difference.
