[QUOTE=shane3fan;1087851]I wonder if a ceramic diffusor attached to the end of the hose inside of the housing would make any difference? Or would that be wasted time and energy[QUOTE]

I built one of these back in March and have been using it ever since. My thread is here

I tried the ceramic disk inside and the tiny bubles got sucked up into the outlet too easily. bigger bubbles worked better versus a fine mist from the disk. I also tried a micron cartridge to trap CO2 inside the chamber which worked fine but the micron cartridge clogged and started to grow algea.



I use a dedicated pump to work the reactor which I think is best to avoid impact flow on my canister filter. I get really good CO2 circulation around the tank 4' 75G.

I now chop bubles on intake of powerhead to the inlet of the reactor and use long tubing to pull water from the bottom of the chamber.

I find this system works great, I have cheap home filters at Canadiantire in Canada that are clear so I can see CO2 bubbles inside the chamber. I can also vent the excess CO2 or air out of the chamber with a button on the top of the filter.


I got a 10# CO2 tank to last over 5 months on a 75G with this diffuser running with a PH controller.

Hi all, I tried mine out today after a month of collecting Co2 equips and the cerges reactor that I built leaks the Co2 into my tank for some reason even after I put PVC pipe glue on the top of the output connection where the coupling is.

I'm not by any means saying it's a bad reactor since it still turned my drop checker lime green in a matter of 2-3 hours with 3BPS.

Just an update for you guys.

How does the Cerges reactor compare to Tom Barr's DIY venturi reactor? Could you do a venturi loop for this one as well, I don't see why not, other than perhaps its not necessary.

Thanks

Fred

I have one of these as a DIY canister filter/CO2 reactor on my 20L powered by a maxijet 600 ran externally. runs terrific and dissolves all CO2 that is pumped into it

maybe try putting some filter media in it to help break the CO2 up a little bit. I was getting little bubbles coming out of the outflow until I did this

The reactor is supposed to go on the outflow side of the canister, correct?

Any water filter housing that you can find at a hardware store will work fine.

This is the one I just set up:

http://www.homedepot.com/h_d1/N-5yc1...atalogId=10053

I am using it with a 80 gph water pump. It dissolves CO2 just fine but, I just ordered a 200 gph water pump to increase the circulation.

Is there a disadvantage to using a smaller filter housing, say 5-6" housing, versus the size that has been shown so far? I came across this filter housing while researching this topic. The inlets are 3/8", so that could be a disadvantage for some. But... it's just a bit over 7" long. This could help to save some space in the stand.

I think there would be less contact time with the Co2 and the water in the reactor. You might also get more micro bubbles in the outflow.
I'm using one of the full sized ones with the clear housing and really think this is the best designed reactor yet.

I tried the 200 gph water pump and it was noisier and released a lot of bubbles into the aquarium so, I went back to the 80 gph pump and it works better. The Cerge reactor works well to dissolve CO2 but still spits out bulbs and a little mist. Much less mist than a powerhead with the split impeller mod. I wouldn't try a smaller housing, I think it will release quite a lot of bubbles.

My canister filter has 5/8" ID hose and I can't find the barbed fitting like the ones used here. Have tried HD, Orchard supply and Lowes. Does anyone know where to get a 3/4 threaded to 5/8" barbed fitting?

how much water are you pushing through your reactor? thanks.
