hi guys,
im back again. Well i got the reactor built now, with a couple of devations on the parts used in the original thread. Thanks, to samh for referring me to Reece here in Australia, when i got to the desk there, i showed them the picture of the parts i needed and they said they had never seen them before. But they did find a alternative set of parts i could use. They were a little expensive, not for a plumbing shop expensive, but just due to the high quality of the parts i was buying they were expensive. I used regular PVC 2" pipe for my reactors body, all up the needed parts came to around $60 Australian dollars. The pump i used was a Deltec AquaBee UP1000, again very expensive pump, they go for around $100 Australian dollars here and pump around 1000 LPH / 265 US Gallons per hour. I needed the extra grunt that this pump has because my reactor body is around 18" i think all up. I will measure it later, as will come some pictures of the reactor that I've built.
Now, i just need a little bit more help with regards to getting the venturi to work. I have, my pump which is just a powerhead, inverted and i have the venturi line coming from the reactor 2.75" inside the reactor body with the line attached to the diffuser impellor intake. I have 19mm irrigation fexible pvc pipe coming from the pump outlet up and back, into the top of the reactor fitting intake. Then water runs through the 2" reactor pipe downwards, to the bottom fitting outlet, and then back up to the tank again with the 19mm irrigation fexible pvc pipe. Now i injected some CO2 gas into the reactor via the top CO2 line which extends 12" down into the body of the reactor.
Thats how i've got it built, but again, the venturi does not seem to be working, with it all switched on and running, CO2 injecting, i have bubbles coming out from the powerhead intake up and out of the water. Also i noticed, there is no flow coming from the powerhead outlet coming from the reactor.
