Setting up a 180 gallon that has two corner overflows, each with two holes cut per overflow. Each overflow has a 2" and 3" hole cut. Ideally I would be able to set up dual herbie drains in each over flow and route the return line to behind and above the tank, but the wall trim and canopy impede running a return line above the tank trim.
I am considering utilizing only one overflow to accommodate the herbie style set up, with a full siphon and the semi-wet secondary drain, in one over flow. Then the second overflow I will use the 2" hole to run the return line, and set up the 3" line as a completely dry emergency line. I know that the return/emergency overflow will not function as a skimmer and the actual water in the overflow has the potential to stagnate, but I can alleviate this by drilling small holes in the return line standpipe to get some circulation.
The other option I was considering is running a durso drain in each overflow, and the other hole will be used for a return line from each overflow. I like to keep my sump flow very low so I dont think this will cause alot of noise, but I am then missing out on an emergency drain.
Any opinions on if the designated return/emergency drain overflow will work out would be appreciated.
Thanks,
Terry
