Help With a CO2 Reactor for my 125 Please?

[Steveo McNello]

This is the last thing I need to complete my co2 system. Everything else I have already bought or ordering today. My question is, do I need something like this?

Or is there something suitable for cheaper? Any suggestions on what I should buy? I'm leaving DIY as my last option because I'm not too handy. Or is there an easy build?

Thanks!

Too small IMO:

Beside you can also buy those a lot less from $30-$50 in plant forums web-sites
You can make your own to handle a 125g

I would look into a Large Needle Wheel or a Mag Drive w/Fractionating-impeller to give that extra flow in your tank

That could work there a lot of ways to mix the co2. It doesn't have to be big as long as its mixing the co2 effectively. That reactor has to be hooked to a water pump or inline from the outlet of your canister. Its how it enters the tank will depend how efficient it is. You can go with a long spraybar to get the mixed co2 water dispersed through out the tank.

This is a Co2 Reactor, not rocket science... $110 is WAYYYY to much

This is exactly the same as that $110 reactor for $9. Size: 5.3cm Ø x 32cm height

I don't get the whole, "internal use only" on those.

That means its not water tight, but with some PVC cement you can make it water tight. Has anyone else used this?

That E-bay page has a video of the smaller one so you can get a feel for the size of it.

my vote would be for the inline atomizer. I have one of these in my tank and I love it. http://cgi.ebay.com/Up-aqua-CO2-Ato...ultDomain_0&hash=item3a5ce90417#ht_2485wt_905

I can use that on a 125 gallon tank? And how about with FX5 hose? 1" inside diameter.

 

[Rockhoe14er]

in that size tank you might want two or have a ton of current in your tank to help disperse it. I guess that is a pretty big tube i wasn't thinking about that. You could find some kind of rig to switch your ~25 mm tubing to fit the 22 mm. But i guess that does throw a bit of a wrench into this idea. I've never tried it before so i'm not sure how it would turn out

 

[Steveo McNello]

And the fx5 return current should be plenty. I'll look into it!
