I just wanted to thank you guys for this incredible thread! I am in the process of setting up my first planted tank (I have 2 reef tanks and I used to keep African Cichlids many years ago) and have bought everything except the CO2 injection and lighting. I came VERY close to buying the Fluval Pressurized CO2 Kit, but the reviews were iffy and refill CO2 cartridges are expensive.

I am going to order the parts tomorrow and will work on putting this together next week. I will post pics when I am done.

Any thoughts on the inexpensive Adapter/Gauges available on eBay?

Ebay link was removed, but they are the "all-in-one adapters with the gauge built right into the unit. Description is:

"THIS LISTING IS A DO IT YOURSELF ADAPTER TO CREATE CO2 INJECTION SYSTEM FOR YOUR AQUARIUM / PLANT TANK FROM A COMPACT SIZE CO2 TANK THAT CAN BE REFILLED. FITS ON ANY STANDARD PAINTBALL CO2 TANK AND CAN SHUT THE TANK ON AND OFF WITH KNOB ON TOP. THIS ADAPTER INCLUDES 2 OUTPUT PORTS, 1/8 NPT, AND A 1500 PSI GAUGE INSTALLED IN ONE OF THE PORTS (WITH LOCTITE). REQUIRES, DO IT YOURSELF INSTALL, OF YOUR CHOICE OF SIMPLE ON OFF VALVES (CAN BE PURCHASED FROM HARDWARE STORES) AND LINES RUNNING TO YOUR TANK. ADAPTER ALSO FEATURES 2 O-RING PIN VALVE DESIGN AND DEGASSING WHEN THE KNOB IS UNSCREWED"

Trying to get my hands on a "free" paintball CO2 tank, otherwise I will pick one up next time I go to Pennsylvania or New Jersey.

Best,

Alfred

I just bought a needle valve that looks really good.. It goes up to 3000psi and is only 15 bux, and never opened.. They still have 10 more I think:

it looks legit, i watched a you tube demo of it and it just screws on no prob, so i just bought a 20oz tank online and a diffuser, hopefully im good to go. i really wanted to do the diy but was worried about the needle valve consistency. plus i have fishies so i dont wanna gas em thus the need for the solenoid. ill post on here how it turns out though.

I decided to go with a paintball setup for a 9 gallon shrimp tank im setting up. I already have the on off valve w/ gauge, and a 20 oz co2 tank. I was in homedepot the other day looking at needle valves. They had both that are in the pictures at the start of this thread. The second one that is a 90 degree is a compression valve. Will that be good enough to withstand the pressure and be able to tweek to 1-2 bps. Im new to co2 setups

I can't believe no one's hurt them selves with one of these things yet

This is a how-to that seriously should be looked upon as a liability to the forum and should be DELETED.

It has worked great for me so I don't think this thread should get deleted.

Just out of curiousity wouldn't it be safer to use this http://www.amazon.com/AQUATEK-CO2-Pa...ywords=CGA+320 along with this? http://www.amazon.com/Kegco-Premium-...=c02+regulator

Thanks for your input. In terms of safety Just wanted to see if anyone went this route instead of using the needle valve from home depot.

What is the secret to getting a consistent bubble count with these needle valves? I am finding it will hold a steady count for a few hours, but then when I wake up in the morning, it has slowed. I don't mind it for now, since I don't have any fauna yet, but this could prove detrimental once fauna is introduced.

I know that just the slightest of adjustments can really skew the count out of whack in one way or another, it's only been a week since I've had this set up running, but it is growing a bit frustrating trying to keep it steady at a certain rate.

Any tips?

If I can't get it figured out, I'm thinking of getting an Aquatek Mini.

Unfortunately, as you have found out, these needle valves are not really meant for the fine adjustment of gas flow that we require in this hobby.

You are better off getting a quality needle/metering valve for this purpose.

I have reserves against those all-in-one pressurized CO2 setups, but some people swear by them.
