JJ,
If the 1050 pump already has a venturi, won't THAT break up the c02 somewhat? What if you DIY modded the 1050 gph pump impeller for needle wheel? Is the venturi on the intake side PRIOR to the impeller?????
You will have way too much pump for almost any reactor you build at 1" diameter...that size pipe will NOT flow more than 500-600 gph if that...
I personally would just use a rio 180 ($25) and mod the impeller and drop that into the sump for c02. The outlet of the small rio should be directed towards the main sump (1050) pump for distribution..
You will have to T/split the flow of the 1050 pump to the reactor and direct to tank, and then either merge together or go separate to tank. Since you only have ONE drilled outtake you will have to merge unless going over the wall.
This is more complex plumbing and can be avoided using the above scenario....
Or one of the new atomizers seems to be doing the trick for some users...
Nothing wrong with a reactor, but just a bit more complex to plumb and feed it properly is all..
When I had a sump, I ran my AM1000 reactor with a mag 5 (iirc) that was separate from the main sump pump. I simply directed the outflow of the reactor into the intake sponge of the larger sump pump for the tank returns....that worked well...but requires a separate reactor pump which in your case could be....needle wheel as well. so chop/mist the c02 into the reactor first.....
Your choice of course...........
