critique my sump design

[adtravels]

I am getting a 2ft cube tank and have the oppertunity to design the sump.
I am tight for space so have included a fw reservoir in the sump.
there will only be room for the electrics. I dont want baffles as The skimmer i have is pretty good with bubbles and they will also have to pass over a small fuge in the middle., the first section is large to accomodate the skimmer which will clamp on the first baffle its a hang on that will sit in the sump.
The water will go right to left as you see it and I plan on using a pump rated at 3500lph minus head loss (e.g ehiem 1262) and 1\2 inch piping with some ball valve taps to control flow.
The overflow will be a weir in the back corner i.e triangular shaped.

Please comment if you notice any problems or have any suggestions for improvement
thanks.

you will probably gt bubble from the fuge chamber to the pump chamber, you need a bubble trap of some kind or the water will fall direct on the pump and cause lots o micro bubbles.

add more bafflese in between the fuge and the return chambers to make sure you are free of microbubbles
