Hey guys: Thanks to the new house and my wife's generosity in turning over the basement to me... I get to setup things however I like. I plan on keeping my 120 main tank going and adding into it a 100 gallon rubbermaid stock tank as a sump with my old sump (50 gallon custom by Summers) as the refugium somehow plumbed all together. I have a 1.5'' drain and 1'' return in the built in overflow. Anyone have good pictures as to how you setup a 100 gallon stock tank plumbed as your sump to a main show tank? I just ordered new bulkheads and now I will head off to HD to pickup piping for the new setup. Any ideas would be great.
