As of today, it went down to 800 psi. I'ts been running a few weeks now, at max it was at 850psi. Been running since I made this diy thread.

When the gauge drops, it doesn't drop straight to 0psi. Since it took a few weeks to use up 50 psi (base on 850psi being max on paintball co2 tanks) I would have to say it will last a few months. I know for sure more than 5 months to say the least. It will slowly drop, like within a week it would slowly move the needle just a bit. So there's no straight drop indicator. I do know that gas expands and contract due to atmospheric temperatures, so maybe sometime in the coming winter, it will be used up quicker. But at the moment I'm looking at at least well over 5 months on one refill at 2bps.

I actually refills mines when it's near 50psi. I don't let it get to fully empty.

Another thought on EOTD...if it's a 20 or 24 oz. tank, how much could it really be dumping?

So far I've found this unit to work well. My only gripe is that I have to keep adjusting the needle valve due to temperature changes around the bottle. From what I've read though, this is common even to larger setups. It's just tough with this needle valve. I'll probably upgrade to a Fabco NV-55 and also see about insulating the bottle.

I had EOTD dillema's as I use this on a small fluval edge tank. It happened on my 88g canister rig in this edge tank that's why I was a bit worried.

It's also tough on higher quality needle valves.
I use a parker valve at 2000psi and still it is hard to do adjustments.
I use pliers to grasp and help in fine tuning the knob.

Is there a rule against posting links to products off-site? I had two people PM me to ask what parts I used... I got them off of Amazon, and I'm happy to post the links here for everyone's benefit if it's OK.

System has been up and running for a few days without issue. I made a bubble counter today out of a check valve and a syringe, which is also working like a charm.

Thanks a ton for the guide!

Looks awesome! How's the fine tuning of the Swagelok B-ORM2 Needle valve?

Couldn't tell you...still have to get the tank filled and get a psi gauge. Also waiting on my drop checkers in the mail.

Thank you so much for this write-up. I was looking for a way to put co2 in my 10g without spending money on a huge system.

Capsaicin_MFK: I'm interested to hear about that needle valve as well. Let us know how it performs

this is my first post here

i am new to planted tanks and have been searching for an affordable co2 rig for a while
this is perfect

using your instructions i was able to assemble a system for ~$60

thank you for sharing this.

one question. does anyone know if the tank can be placed on it's side? or should it be upright when in operation. i know they are often sideways or at an angle when attached to a marker but i'm unsure if it will work laying on it's side in this setup.

thanks

I think it's best to put it upright while operating.

it should be placed upright to prevent liquid co2 from getting into the line as that would surely cause an unwanted CO2 spike as well as safety concerns.
