Anyone have experience using a SunSun 304/404 with either a Cerges or Griggs reactor in-line and can comment on flow rate reduction? Size of reactor housing (and maybe inlet/outlet diameters) info may be helpful.

What @Immortal1 stated about smaller internal holes on Cerges whole house filter housings makes sense. Anyone have a particular brand of WHF housing that had large holes/didn't reduce much flow?
I assume Griggs style reactors would not have the same issues (small holes significantly reducing flow)

I was thinking of doing a 20" Cerges since I liked the WHF housing appearance better than PVC Griggs, but if flow rate would be reduced much more with the Cerges, or require a by-pass to be made with PVC, then I might just go straight ahead and build a PVC Griggs and avoid the hassle (likely save some dough too).
For the SunSun mentioned above, the Cerges housing should have 3/4" inlet/outlet threads right, not 3/8"?
If I went the Griggs design, I would probably still do at least 20" in length (standing tall). What diameter pipes should be used?

Anyone have links from Amazon for a WHF housing? The one I got at lowes has inlet and outlets that look super restrictive and is cutting my flow. This is for a 100 gallon. And a link to the center pipe, I used tubing but the Co2 is eating it. Like a defacto setup that is tried and true.

@WaterLife I know the adjustable water filters with a built in cut off on top, have much smaller holes than the regular ones. I made the mistake of buying one of those first, thinking it would be a good thing, then noticed the holes inside were like 5/16" dia. That's just a guess, but they looked tiny. Had to go buy another one

I am reading into the various DIY Cerges CO2 reactors for the 330g tank I am building. I came across this thread, which looks it could be very useful to read from Tom Barr, but all the images seem to be broken links:
How To Build A Cerges CO2 Reactor - Aquarium Plants - Barr Report

Was this design reported also anywhere else by Tom, where images would still be active?

This is the dual venturi build from Tom Barr (modified Rex Grigg design)

The link you posted, the JPG (JPEG) links aren't working for me (maybe you have to be a logged in member? or the OP deleted the pics from their computer), but all the other pictures throughout the thread display for me.

Any way, if you still can't see the pics on your linked page, the Cerges build on that thread is just a typical Cerges build.
