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.

inTank Chamber Plug for Fluval Evo 13.5, 52L and Fluval Spec 16, 60L

Improve the flow in your Fluval Evo 13.5 and Fluval Spec 16 aquarium. The plug blocks off the hole in chamber two, improving the track of water forcing it into chamber one, and keeping the rear chambers more clean.

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