filter roller install help

[LowDime]

I am working on setting up my sump and what nots. i have a 80 low boy with a 24" cube sump with 4 sections. the main section is going to house my filter roller, i was thinking about turning the original filter sock area into a fuge area. and then i have the section behind the filter roller that feeds the return pump area. My question is would the fuge be better suited in the larger 2nd area that feeds into the return chamber or would it work in an area that is 7x6 or so dimensionally.

My next question is on plumbing all of this. The return pump area is very small and tight in this sump so i can't run 2 pumps or even a larger pump. I am currently running a small sdc 3 iirc. So i was thinking about using a manifold on my drain to feed a small amount of water into the fuge. ( never succesfully had one.) Or so i run a bigger pump and manifold off that to feed the fuge and uv light.

The last pictures shows what the order should be but i was constantly fighting detritus in the bottom of chamber 1 because I didn't have enough water volume from a single durso style drain to push the water up over the lip and through the filter sock. so all the waste would just gather in the bottom and then spill over to chamber 2. I could only run the return pump at 50% or it would constantly gurgle and make a ton of noise

Roller filter should go in chamber1 so the unit gets all the return water, even if you have to modify it.
Durso drains do not flow a lot of water, you would be better off with a Herbie system.
A refugium really should be in a separate large tank to be effective. Running something like a lighted chamber would be better.
Wherever you put the return pump is where your ATO has to be.

i am switching it over to a herbie and doing an over the back return set up so hopefully that will work better for the drain. I dont know if i can make section 1 big enough to fit the roller or not, will have to really measure before cutting to make sure i keep the structure strong enough. My ATO and return pump are normally in #4. Now just to figure out where to put the uv

The uv requires specific flow rates depending on the size.
It can go either off a separate pump, the drain line(if enough flow), the return line if flow is correct.
It all depends on flow.
