Took me a while to get the stuff together but its finally all done.
The reactor itself was very easy to build. I used a simplified design because i didnt want to spend too much on fittings. Installing it was a pain in the butt. Had to redo all my piping and modify my hood a bit, cause its a Jebo style plastic hood which used to have its own wet/dry filter. Here is the reactor put together:
All the equipment goes inside the 24gallon tank cabinet, which isnt all that big so its kinda crammed in, but i think i did a good job laying it all out. Here is the pic of it all. Reactor, filter, co2 cylinder.
And this is just the reactor and co2 side of it. You can see the reactor in the back left hand corner. Its held upright by cable ties to the cabinet.
Here is the Dupla bubble counter i bought. I gotta say its not the best thing ever. Far from it :S But i decided to use it anyway. I had to return two of these before cause they were leaking. Just behind the counter you can see the Clippard brass check valve. I put it there instead of before the solenoid because i wanted the water pressure to stop before it reached the bubble counter. I didnt want the checkvalve to work, and then have the bubble counter break and dump the contents of my tank onto the floor. I think its safest to put it where i have it at the moment.
Like i said the bubble counter isnt all that good. It comes with a built in check valve (circled on top). But i put another plastic one under it (circled at the bottom). Just incase the first one failed, i didnt want water going into the solenoid. The plastic valve should be fine for this as there should be no back pressure from the bubble counter anyway (bar gravity) due to the brass check valve before reactor.
And thats it. There are some little bubbles coming out from the outlet, but i'll live with that. Its probably because i dumped a lot of co2 into reactor to start of with. Plus i cant fit a taller reactor inside the cabinet. Anyways, thanks Rex for the design of the reactor and answering my Q's. Thanks to AussieTanker for giving me info on where to buy the parts here in Sydney. And also thanks to everyone that helped out in that Rex Reactor thread
