Posting this during work so I'll keep it short lol but will answer any questions or respond to anything anyone wants to add... Tank is a 80g built in 2017 got for almost nothing. Overflow is a reef synergy shadow, sump is a 40g breeder still need to silicone in the different compartments, pump is a jebao dc 2500gph. All return piping is 1 1/2 inch and plan on running the pump around 2000gph which should give a lot of flow.. also have the surge protector on cabinet rollers so you don't need to crawl inside or behind the stand to mess with the wires. Will post more pics later.... what do you think?? I'm happy with it. Going to plumb my other tanks into the sump at some point.
