Because the understanding that pressure is required for dissolution only became known to the hobby last year. (It's not exactly dwell time that's important.) If you understand this concept of pressure, you can do things to increase it. Numerous ways to do it - I've suggested some.

A problem I suspect is the 20" housing (short return head height) + 1/2" tubing = very low pressure in the reactor. The pump output may be enough but the lack of pressure is the problem. Thus, a 10" tall housing may actually be better, though I am not certain.

ltb420 The original venturi reactor design that called for the 200 GPH pump was slightly less than 2" wide using a water changer tube.

oh, i didn't realize it was 4" wide. But you are right about all the bubbles going right out of reactor. It was microbubbles which has been dissolved by reactor. The flow was really a lot, I'll play around with it today and see.

i have a 20" btw.

So I upgraded tubing and fittings to 3/4 on input side of reactor. Hook it to quietone 4000 via 10 ft tubing with 991 gph. I left the eheim tubing on output side of reactor. The flow is tremendous and I had to dial it down using ball valve. I'm going to test co2 today since it got late last night.

I think the pressure is going to be really good.

The 2000 GPH may be too much flow for your 4" reactor. The 1000 GPH may be a better option.

Solcielo lawrencia Can you take a picture of the entire setup?
02-19-2015 07:33 PM
andyl9063 I'll just stick with 1000 gph. Increase tubing size to 1 inch. We shall see what happens.
02-19-2015 07:18 PM
Solcielo lawrencia You'll probably need to restrict the outflow. Also, 1/2" tubing is really small. Not a lot of water volume means less pressure.

The tank is 6 ft tall. Probably a few more feet for additional piping if running straight through reactor.
I wonder if there's any downsize to this.

andyl9063 How do you guys feel about a 2000 gph pump? My sump pump is 2000 gph with probably 6 feet of head. I hate to have so many devices inside the sump along with power wastage.

ltb420 As stated above the pump is probably your weak point. With a larger pump the gas bubble is dissolved rather quickly once the CO2 is shut off so it may solve both issues. Going to 3/4 tubing will not hurt either. I use the lee's tubing.

co2 enters needle wheel pump rated at 200gph. NW pump straight to cerge reactor via 12/16mm eheim tubing, co2 water travel down 20" reactor housing, then up pvc tube and exit via 12/16 eheim tubing. Pump is before reactor. It is plumb according to flow on reactor (travel down housing then out via pvc tube).
