Still fine tuning my griggs and just wondering. On one hand seems like there would be no difference, but on the other hand seems like there might be.

Thanks so much, super helpful. I'll try it out.

IUnknown, having built several Cerges reactors I can offer a few bits of info regarding your situation.
Some of the whole house filters have fairly small holes leading into and out of the filter. This ends up causing the poor flow at the tank output. One way of fixing this is to add a regulated bypass to the Cerges reactor.
As for your reactor filling up with air / cO2, this would be an indication of running too many bubbles per second for the amount of water flowing thru the reactor. Not sure why, but it seems if you have a little slower flow rate thru the reactor, it seems to absorb the cO2 faster. For my system I run 5-8 bubbles per second without issue. Anything more than 8 and I start building a bubble in the top of the reactor.

|IUnknown||I have been having issues with my cerges reactor filling up with air, and worried that the flow rate has been reduced too much. Haven't read the whole thread, but does the DIY Griggs style reactor provide more flow? Why is air filling up?|

I guess that's why these things should be made sickies - or does that not prevent the image source from disappearing I wonder.... [emoji848]

|seandelevan||I ditched the Cerges reactor after 5 years because of lack of flow. It was pitiful. I needed two eheim 2015s at one point. The one connected to the cerges reactor was at best a weak trickle...the one without was full stream. Finally went with a DIY Griggs style reactor and it was good to go. Didn't need two filters taking up space anymore. I would do a cerges again if I had something like a fx5 or fx6 that had over the top flow.|

|Patriot||I would get the largest you could possibly fit. The bubbleight not have time to diffuse in such a small space.|

Would this size work if I want to build the reactor? I have a small 17 gallon and my stand is already crowded.
7-3/8 x 4-5/8 inches (187 x 118 mm)

I actually have a 20" 'Big Blue' that I was using for my house before I upgraded that system, so I would just need to swap it out, but it's so damned heavy when full that I don't think my stand can take the torque it would apply to one brace. I have a feeling, though, that it won't make too much of a difference.

This is the flow I get using a 20 inch housing with a Sunsun 404b "525" GPH.
Looking into upgrading to a Fx6.

I'm setting up a 46 bowfront and built one of these Cerges reactors. In my old 20 Long using a diffuser connected to the inlet of my HOB filter, it would take hours and very high bubble count before my drop checker would change to a light green color. Using the Cerges, should I expect the time for the drop checker to change color to be about the same or should it happen faster? How about co2 bubble count? In my previous HOB diffusion method, I know there was a lot of waste because I can see the bubbles going up to the surface inside my HOB. Seems like the cerges should be more efficient and much less wasted CO2?
Bump: btw, in case anyone is interested, I found and purchased this filter from amazon. It cost about the same as the lowes/homedepot one but it is clear
With this filter, I use a regular 1 inch pvc pipe cut down to length as the center pipe and it fits snug without glue
