I'm thinking about using a 20g long to make a sump for my 75g system. I'll attatch a drawing of what I had in mind and If anyone has feedback I would appreciate it. I don't really think a bubble trap is necessary but it may be. Should I switch the fuge and skimmer sections? My thought was If the fuge got the water first it would have more time to process it before the skimmer got to it. I don't know... this is my first sump build so any help would be great!
