What Size Should My Overflow Plumbing Be?

[Palster]

Thanks for the sound advice Untamed. I am somewhat familiar with the "Herbie" method and it is one of the things I have considered. I was thinking that I probably should go with 1 1/2" plumbing but I just needed someone to confirm this. I do not get the opportunity to see a lot of other tanks and what other people are doing here in Kelowna so I rely on this site and the Internet in general for advice.
