Looking good! I'm hopefully heading over this wkend to look at a new (used) tank, thank you for that info btw! What are you planning for a return pump? What GPH? I know you've had larger tanks before so I figure you have more experience. I'm just interested to see what volume I should be running when I get a bigger tank (90g-120ish). I bought two 1.5" bulkheads I was planning to use as drains, I plan to do a coast to coast overflow on the left side of the tank. I was only planning 1 return, but I might need to do 2? I have a Mag7 on my 40b, and plan to use that as a return for a little while, but will probably upgrade at some point.
