|flight50||I bought parts last summer to build one but never got around to it. Since my current project got underway with construction, I went ahead and went with the Cerges Reactor. It's in place but not operational at this time. Considering I never returned the parts for the Rex Reactor, I will go ahead and construct the Rex reactor and install it on my 125g plant only grow out tank. I'd like to be able to compare the two.|

|gnatnog||I know this thread is ancient, but i'm interested in building one of these reactors. I'm hoping someone has the plans still since the links don't seem to be working anymore?|

|jaidexl||The Rex reactor built the same way Rex did achieves 100% diffusion, or at least to the human eye it does. So if you're replacing a diffuser that creates visible micro-bubbles then yes, you may need to drop your output a bit.|

3.not really understanding the BC question, it is just for reference and doesn't really mean anything, you use the DC reading to fine tune your output, then the BC as a visual reference for the particular tank.

|newbieplanter||I am wondering how people are measuring the level of CO2 in their tank after this unit is installed, an how long after hooking it up do u see the changes? If u use a drop checker did it turn green or stay green within mins/hrs, or did u have to wait a day or so. Those with bubble counters did u have to turn the output down or up?|

I decided to rebuild and recommission an old Rex reactor.
I didn't think the injection through the brass barb was completely ideal so I placed two small o-rings around a roughly 1.5" long piece of co2 tubing, then super glued that on the inside part of the brass barb to extend the injection point to the center of the water flow inside the reactor. I found a can of "hammertone" Krylon Fusion at hobby lobby on clearance for three bucks, I think it turned out kind of nice.
I blasted hot water through the reactor with a python for an hour after letting the PVC glue and paint dry for two hours outside before hooking it up. I added activated carbon to the tank to absorb any acetone that may be leaching into the water, I also put some purigen in the filter the day before.. the stuff is amazing.

|yobofofas||I'm curious; I switched out my spray bar for a clear PVC spray bar and I'm wondering if the increased flow will cause outgassing. I've got the spray bar just below the water level pointing up at a slight angle to create surface distortion. Am I just completely out gassing all the CO2 my Rex Reactor has mixed into the water?|

|yobofofas||Hooked up the reactor today and it works great. No flow issues at all. I went with 2" PVC and an 18" length. Seems to work great. There are a few micro-bubbles every once and a while but I'm pretty happy. Thanks REX.|

|yobofofas||Just built my Rex Reactor today but can't pick up my C02 tank till monday. Bummer. But I do plan on getting it hooked up inline to make sure my flow isn't too limited. Did any of you have flow issues? If so is it just as easy as getting a more powerful pump?|

I built one a few weeks ago and I have my co2 maxed out with no micro-bubbles only nice pearling plants.

Don't see the point: if the reactor is built right, it will dissolve 100% of co2. No bubbles.
