DIY Co2 Regulator


Recommended Posts

Hey everyone! I'm going to start injecting co2 into my 10- gallon planted betta tank. After spending the last few days pricing things out, I decided to DIY my own co2 regulator. Maybe in the end it won't save me money, but it will be fun to learn something new. 

I'm going to post updates, the build, questions, links to information, and how well it works here. There's actually some really informative threads on planted tank and saltwater forums. I need to read through them and get a parts list.

Plus, at the end of the day, I'm sure I'll need input and some advice from someone who's actually done this.

Yesterday, I spent part of the day scouring eBay for regulators. I looked at listings for Mathesen, Smith, and Victor regulators. There's a lot of listings for older models right now. @Mmiller2001 recommended finding a 2 stage regular. 

For $50 I found a Uniweld 2 stage RHT 8013 co2 regulator. The listing said open box, never used. The box looks like it was mauled by a bear but the regulator looked new. I ordered that. Next on my list is a soleniod, needle valve, and bubble counter. Back to eBay.

Here's the manufacturer link in case anyone is curious.

First update!  

The regulator shipped and should be here towards the end of the week. I've been reading through a few threads on other forums, and random posts on reddit. One of the biggest issues that has been popping up is locating various parts at reasonable prices or its just not available.  Another hurdle is when you find a posting with part numbers, its from 6 years ago and the current number may be different. 

Here are some of the most helpful threads from other forums I've found so far.
