Ok. I am not a plumbing/piping guru. In fact, I'll be honest, I don't even really know the difference between PVC and ABS piping(not even sure I need to). I have some bio-balls that are approx. 1.75" in diameter, so a 2" PVC will be needed for the middle section. I read and printed the PVC plans for a Co2 reactor at http://www.hoftiezer.net/personal/aq...co2reactor.htm
I realize, however, that this can be modified, but since I know basically nothing about the subject and have never so much as looked at pvc piping in my life, I like to stick to the list. Tom Barr showed me a great reactor that differs from this slightly, but the basic idea is there. I went to Home Depot and was unable to find most of the parts, at least in the same measurements, so all I ended up getting was the: 1"x1"x1/2" NPT reducer tee (what does NPT mean anyway?) for a dollar or less. Does anyone have a suggestion or maybe another helpful design I might check out? I am considering checking out some online sites like:
since I figure I'd be able to more easily find what I need, but I would prefer to not pay for the shipping as the whole idea of DIY is keep the price down.
Another thing to note is, my Eheim filter tubing looks to be around 1/2" in diameter, although the actual tube says 12/16mm, so not sure what they mean by that. I also would need to find the nipple fitting for the inline Co2 tubing as well as all the appropriate pvc parts. If anyone can offer some help, I would greatly appreciate it!
