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.
