I am going to be setting up a 240g and was wonderging if I could use a large sump-wet/dri set up. I want as much water capacity as possible. So would it be ok to use a 100-150g for the sump? I also will be setting up for a 200g and 180g and want to use same type of set up, porportional to size. Let me know your thoughts!

i like overkill
