About how much would a 10 lb co2 tank and everything else cost ? about how long would this last on a 20 gallon tank or something similar like a 29 gallon ? Also how tall is a 10lb co2 tank ? i just want to know before i start building my stand in 2 weeks.

The price for a 10 lb tank really depends on where you live, whether it's new or used, steel or aluminum. There is no way to give an absolute answer other than that at this link they are $73 + Shipping. And that cylinder is 20.5" tall.

How long would a 10 lb tank last on a 20 gallon? Again there are a lot of variables there. But suffice to say at a very minimum of a year.

Beyond that you really need to narrow down "everything else".

A YEAR!? WOW! I had no idea pressurized could last so long, I always figured around three months or so. So pressurized on a nano would last almost forever eh? haha.

CO2 tanks are a little expensive here. I had a 15 pound that was $85 and a 6 pound that was also $85. That price includes filling though.

My manual regulators are $112 shipped. And of course you can purchase one from me.

I have two CO2 systems in the house. One running a 20H 24/7 with a 5 lb cylinder. I get about 16 months on that system (lousy diffusion method). The other system is a 20 lb cylinder feeding a 55 gallon and a 29 gallon 24/7. I got 17 months on that cylinder the last fill.

Having the proper tubing and no leaks makes a huge difference.

Rex, I'd like to know a little more about your C02 set-up :D

Are there any drawbacks to leaving your C02 on 24/7?

How many bubbles per second do you run and are you using one of your reactors or some form of in-tank diffusion?

What kind of C02 tubing are you using?

take a look at his guide and you'll answer a lot of your questions.

I got a 15 pound CO2 tank off of ebay for $73 shipped UPS ground. Locally, a 5 pound is $75, filled. My regulator is from *here*. Rex's handmade regulator is basically the same, but less pricey. I got my CO2 tubing from Rex, and I built a venturi reactor.

"I use DIY external reactors . . ." - Rex's Guide.

However, here in this topic he says he's using a lousy diffusion method.

Hmmmm?

Also, I found no information in the guide on what tubing Rex uses.

However I may be wrong and was not looking hard enough.

well since he highly recommends and sells co2 proof tubing, i can only imagine it's what he uses.

Ah ha! Your right danepatrick. I'm going to assume it's clippard.

The diffuser on the 20 gallon is a Hagen ladder. The tank also has a HOB filter. One of these days I need to get a canister filter for that tank so I can use a reactor.

I have no problems running the CO2 24/7. Bubble count is not really worth much. I can tell you that on the 55 gallon I run about 3 bps.

And all the tubing is Clippard tubing.
