I will be upgrading my current tank to a 65 gallon and would like to make my 40 breeder my sump but am running into issues with how to make the stand without oversizing it too much. I would also like to have the sump sit back 3-4" inches behind the display so that my drain and return lines can be a simple straight pieces of pvc. Is this possible or am I going to have to oversize the stand? The other issue i have is that the sump will have to go in after the tank is up and running as I will have to convert the 40 into a sump and install baffles .
