Need help building an external CO2 reactor.

Thinking of building an external CO2 reactor based on an Asia product that is not available in this county. A little info on my tank, CO2: pressurized, tank: 180g, pump: MagDrive 9.5 with 950g/hr. A few questions:

-Size: 4"x 20" is it too big? should I use a 3" pipe instead?
-The return pipe in the middle of the reactor, is that a good design? How about the funnel at the end of the funnel? How much space from the bottom of the reactor to the funnel?
-The CO2 inlet, I'm thinking of extending it 6" into the reactor, is it about right?
-I took a page from Tom Barr's reactor design and place an outlet that returns water or CO2 to the inlet of pump. Since I will only be running CO2 for 8 hours/day. Is this nice feature still a must have?

Thanks for helping, if you see other problems with this design. I would appreciate feedback.

All I can say is good luck with that design. I was thinking about this today and it might be possible to build something that would work. But I'm going to have to look to see what PVC fixtures are available to use.

Thanks Rex for helping.

Need lots of real estate to accomodate the 3-4 outlets, 4" was picked for that reason. My main concern is having a tube down the middle ...

I think that the biggest problem will be getting all those outlets in the top. The tube down the middle IMHO is not the problem. The rest are.
