Sump/fuge design.

Hey guys. I haven't posted in a while. I'm in the process of planning a 75 gal reef. I got the tanks and have a couple of items of hardware. Right now I'm just trying to work it all out. I made a rough design of a sump and fuge. I have a 20 gal long and plan on having a rubber maid container for the fuge. I know there's probably a bunch of stuff wrong here but i wanted someone to critic it. Just any suggestion would be greatly appretiated.

 

make sure you have 2 ball valves so you can control the flow to the sump and to the refugium

 

Thanks! I forgot to draw them in.

 

It looks good to me !! Hard to tell on the return line for the fuge tho -- just make sure that drops all the way down so you don;t crash the water and make bubbles on the return pump.

 

Got it.
