Plumbing overflow box for 25 gallon cube

[Shawn4455]

So Im close to getting all my materials together to plumb an overflow box, What type of plumbing should I get? This is my first time doing something like this. so my idea is to go with a small internal overflow box and maybe try to do a herbie overflow? Would I have enough room and to make it quiet? Any other ideas regarding this? Its all going to go into a sump and back into the tank.

I am thinking on 1 inch drain into a 3/4 return.

That should work on your cube.
The smaller eshopps are external but they use the herbie set up

Based on your comments it sounds like you are planning to drill the tank - is that correct? Because you are dealing with a small tank IMO I would lean toward an external overflow (like a Eshopps) so you don't use up any more of the limited tank space. I agree that a Herbie drain setup would be nice to have so that you have some redundancy.

Welp, I ended up buying the eclipse M for my tank so I guess it's external, thanks!
