Need help w/ design of 150 gal sump

[k9gunner]

I am setting up a new 210 gal display tank, and have decided to use a 150 I have for the sump. Now this 150 is not your standard tank, it is one that has a wet/dry system built in the back ( I will try to post a pic ). Anyways, it has a built in overflow, the returns it in the center. I am trying to figure out how to add baffles and make this a sump / fuge combo.

My first question is should I try to raise the water level to include the wet/dry system

second, where should baffles be, and how should the water flow?


Note: My display has a closed loop return system, and dual overflows that will run into this sump.

I will try to post pics to make things more clear.

Click on my red house and take a look at how my sump is laid out. It's a 200 gal acrylic tank converted into a sump.

I would take any bio-balls that it may have out. Have your returns enter into this section and over flow into the main area.

Here is a pic of the back of the 150. You can see the wet/dry setup. I dont plan to use the bioballs, however I do want a fuge and a DSB in the main part.

Any ideas on flow and baffles?
