Sump Mods
 

I have included pictures of my sump as well as 3d renders of the modifications I'd like to do ... I bought it because it fits my cabinet well. I'm looking to Mod it to add a bubble trap as well as a small refugium.

The Fuge works out to be 5.3 Gal.
and the return section is 6.4 Gal.

I was looking for input into my design ideas.

Looks great, I would keep the refugium about 3/8" lower them the top of the sump. Very nice compacked sump.
Are you going to do the modes your self ?

that is the plan .. I'm going to have the acrylic cut and glue it myself ... should be doable. any ideas for a drain for the fuge ?

Looks good. I would move your bubble traps closer to the return. This will give the bubbles time to surface before they get to the trap. Anything closer and the bubbles will go around it as they are still in suspension.
The same with your fuge drain, have the outlet close to the start so all the bubbles have time to surface and be stopped by the trap. Other then that it looks great.
