I'm copying everything.....lol
Trying to figure out your fuge/frag area. Looks like you have it draining from the bottom? Water level will be same as return area. You have a drain there AND a feed? Why not place a baffle in there or the drain/overflow higher up so you can maintain a higher water volume for more macro, frags, etc....
Build looks amazing so far. That's the funnest part! Everything is top notch. Looking forward to this badboy coming alive!
It's hard to see from the pic but the line that connects the two sumps has a valve on it. I will be able to control the flow and the water level with that.
