i am building a 12"x12"x24" refugium for my 55 gallon reef tank, i already have a wet/dry sump. can i hook up my fuge to the wet dry? and how do you do this. my tank is not drilled, i have a overflow box.

Can you have the fuge higher than the sump? And can you drill the fuge? If so, feed the fuge with a powerhead from the sump and gravity drain the fuge back into the sump where your return pump is. That's one way to do it. Or you could have the fuge higher than the display itself and feed it with a powerhead and gravity feed the display.
yea leave ample room for spillover water in your sump in case the power goes out. remember, the tank at the bottom gets all the drainage in an outtage.
