Didn't someone besides me try thes out. The couple that I made did a good job and didn't bounce the PH at all. The 2 litre units jus don't put out that much....but are effective on tanks of around 30 gallons.
Pretty simpls setup and easy to maintain....I think it was Sott that made his own bubble counter/regulator...?
I'm interested in this subject too. I haven't done a DIY bottle but I have tried a paintball setup but the needle valve I had wouldn't run consistently so its just sitting now.:(

the 2 liter bottle worked better for me. I couldn't get the regulator on the paintball tank to work right. it would dump all the co2 in the tank in three days. I did get one that was suppose to be made for aquarium use. it just didn't work well.
The co2 didn't effect my PH much. I did find out that if you use a bubble counter that the yeast build up at the end of the air line is a lot less. I also use a glass diffuser to help break up the bubbles so the co2 can be absorbed better.
Ya I have a glass defuser and everything I need to just throw one together. How often do you have to add more mixture to keep your CO2 going good?

It depended on the mix. some will go longer than others. it's about a two to three weeks. That was with two cups of sugar to a tea spoon of yeast give or take a little. I do know that people very off what I use too. I used tap water around 100 degrees. I did try to sterilize everything once. I boiled water and let it cool down too 100 degrees. I didn't see any improvement over not sterilizing so I stopped doing that.
We use paint ball CO2 cylinders from sports athority. A 20oz bottle ($35)(get the first fill free normaly 4 bucks). Order an on and off for the CO2 bottle with Gauge on eBay($5 +ship) and the needle valve at HD($3) teflan tape (.95). Works like a champ. Only problem is getting it dialed in (one bubble per second). After it's set just let her go. You can amost see the plants grow.... LOL.....
It last me about a month and it will never blow up in my fish room..

How long do the 20 oz bottles last??...do they have larger bottles?...nice rig..
This setup is on my new 100 gallon show tank. I have it running now for only a couple of weeks, reports say A regular 24oz Paintball Co2 Tank at about 2bps will last a good 4-6 months. I will update mine as things progress. for under $50 you cant beat this setup...
Here is mini Fluval Flora CO2 Kit will run you 72.00 and that with a 3.1 oz bottle. Online feedback say that it only lasts about a week and the refills costs as much as the inital system.
Do you happen to know what brand of needle valve you are using?

I went the one of the big box hardware stores and got one for under $3.00
The I tried wouldn't stay consistent and leaked bad with that much pressure

Sorry to hear that. I had the same problem at first and me being me would not rest until it worked. Try again later. oh and dont forget the tape on all the parts or it wont seal...
I have almost the same thing. I even put the tank with the gauges on a bucket of water to see where it was leaking. it didn't have a single bubble come out of it. But when I put it on my aquarium the co2 tank was empty in two days. It was a pain to get getting it dialed in. My needle valve is way to touchy.
I here you there. That looks like my setup 2. But once its set you are good to go.
Here is what I got for xmas:
