DIY CO2 reactor questions
I have been reading a ton of posts on this topic on multiple forums and am feeling a bit waterlogged with information. What's my solution? Start another post about it!
I want to switch from my glass CO2 diffuser to an inline PVC reactor, partly because I want to be more efficient in my CO2 use, but also I like a good project. Another benefit is that the design will help me fit my hydor inline heater under the tank without a lot of bent tubing.
The tank is an ADA 60-P (~17 gallons) and the filter is a Eheim 2217. I anticipate that I will have more flow that I actuall need for a tank this size. Hopefully this gives me some flexibility in adding flow-gobbling inline equipment. CO2 is paintball pressurized with an Aquatek regulator.
General reactor questions:
1. What is optimal length and diameter for my reactor? Ideally I'd like to keep it ~16 inches long to make it fit next to the filter. I have a piece if 1.5" PVC cut to this size, but I'm worried that it will be too narrow.
2. Should I use bioballs? Would my chosen tubing width inform this decision?
3. Elbows, tees, or 90 degree barbs? I'll need the tubing going to and from the reactor to come off at a right angle. I could use a 90 degree barb at the end cap or a straight barb from a pvc elbow or tee. I have read that right angles reduce flow, but am wondering if they also create turbulance to aid in dissolving the CO2.
Probably more questions to come, but that's it for the moment.
