ikuzo nevermind, installed it this morning and it works out nicely

ikuzo a question here :

if i use an inline atomizer before the cerges reactor, how's the result?

is it still dissolving co2 or those tiny bubbles will just blow away with the flow through the middle tube?

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 06:33 PM
andyl9063 I'll just stick with 1000 gph. Increase tubing size to 1 inch. We shall see what happens.
02-19-2015 06:18 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.
