Does it matter the orientation of the reactor? ie does it have to be horazontal? or can it be kind of diagonal?

Nice design. I may have to try it if just injecting prior to my return pump does not.

Would expanding the pipe diameter, help any?

I was thinking 12" of 3" pipe?

Muirner

Also how long is suggested? I have a 55 gallon tank and if i make it with 2" pipe i can go shorter, but 1" pipe might be easier to hang, Any suggestions on how long either nees to be?

if you're going to be using bio-balls, i think you can get away with a shorter tube. gomer went with an 8" length, and he had that connected up to a 40 gallon tank, so i don't think you'll have any problems on a 55 gallon tank.

rex grigg uses 18" for a pipe length. i think mainly because his doesn't include bio-balls, and to give that extra bit of time for the co2 to be absorbed into the water. and he went with 1.5" diameter.

Thanks for the advice, I'll be picking up some supplies i hope tonight. I'll be using (i think) 1" pipe, i have found it for about 2$ for 2 feet. I'll be using biorings in place of the bioballs. Hopefully tonight i can find what i need with my dad, last night well ummm was horrible.

or you can go over-board fancy like mine

i'm interested in installing external reactor to new tank i'm setting up. it's a 20 gallon tank, co2 injection, eheim 2222 canister filter which pumps 500l/h. your design is very beautiful, and i am actually contemplating trying to build one...if i dare. i'm not that handy.

a couple of questions: (1) would flow rate be adequate if attached to eheim outflow/aquarium return line? it would run to spraybar which is mounted below water surface level.
(2) is there any advantage to splitting outflow to two return lines (if that makes sense) - one to spray bar and second, more standard return, dedicated strictly to co2 reactor.

thanks in advance.

hey guys, thanks for this great thread. i would like to see more pics of other reactors in-use. i might use this style reactor but have a concern for the size. i plan on using it on my 10g project. would this be overboard or can it be monitored with a bubble counter? could i be comprimising my ph by using something this size on a 10g??

any and all help would be great!

thanks

Melissa, what do you use for a filter set up right now? A reactor mainly goes on a cannister filter thus on bigger tanks. I mean, sure you can do it no problem, you'll just need an external pump. Any size reactor is ok, the bigger the tank the bigger the reactor.

So I got all the parts i needed, and the reactor together, but where i put my brass hose barb i cannot get it to seal. I'll have to take it down tomorow and teflon tape it, and silicone it again. I tried to do it in the tight space under my stand and it didnt work so well.
