tk_yt Posted April 11, 2021 Share Posted April 11, 2021 I wanted to share my personal experience with my first DIY project using PVC pipes. I searched online quite a bit and decided to give it a shot myself. It turned out to be quite simple, so I wanted to share it here in case anyone else would like to give it a try. Parts: 1-1/2" PVC pipe, cut to about 12 inches long (1) 1-1/2" to 3/4" PVC bushing. Get the one that has threads on the inside (3) 1-1/2" PVC DWV pipe (it's a U-shaped pipe) (1) 1-1/2" Sani Tee Pipe (1) 5/8" hose barb x 3/4" MIP nylon adapter (2) I got the hose barb with 5/8" barb for my 16/22 mm hose 1/4" x 1/2" MIP push-to-connect adapter for the CO2 tubing (1) 3/4" to 1/2" PVC bushing. Get the one that has threads on the inside. The CO2 connector goes to that How I got it free-standing: I ended up needing to build a stand as well, because the reactor itself won't stand upright. I found a little part of my old computer desk, that had a metal plate and a connected short metal tube (it was meant to hold a small table top that swivels out). I was able to fit another PVC pipe right onto it and got it to fit snugly by putting a rubber band on the metal tube before putting the pvc pipe on. Then I cut open a few more 1-1/2" PVC pipes and screwed them into the stand, which clamps perfectly onto the reactor! I used bolts and tightened it with nuts on the inside, so that it would be more stable and not have a risk of pulling out eventually. I was really happy to see that I could re-use the PVC pipes to act as a clamp, it made my job so much easier. Reasons for creating this PVC CO2 reactor: I am currently using an FZone CO2 inline diffuser, which ends up sending lots of micro-bubbles into the tank. When I had lights that did not have as high intensity, I didn't notice it much. However, when I switched to using a higher intensity light, it became very noticeable, and I don't really want to have that 7-up effect I thought it would be really cool to try and building something using PVC! It's super fun 🙂 How it works: The idea of the design is that water will be flowing from the top of the reactor, downwards and then out from the bottom The CO2 line injects the CO2 from the top as well, and as the CO2 gets pushed down, it will try to rise up and keep getting flushed down, until it dissolves into the water The idea then is that any water that is able to flow out, should only contain dissolved CO2 I decided not to have any bio balls in there, because I won't be able to get in there and clean the media when it eventually gets dirty As of writing this thread, I have not yet connected it to my filter. I am waiting on my new filter that will be more powerful (Oase Biomaster 300), so the flow won't be restricted too much. Once I have it connected, I will update this thread with more information! 2 Link to comment Share on other sites More sharing options...
