I’m looking for a 20lb CO2 bottle for my daughter’s aquarium. We need it to inject CO2 for plant growth.

A Pepsi or Coke fountain service uses lots of those. Welding supply stores also rent/sell CO2 tanks.

if your close to lubbock or east texas (ill be that direction next week maybe)

i have one in my garage!

if not…. check craigslist. or you can rent/buy one from a welding supply store. (its less then 20$ to refill)

and a 20lb is a large cylinder. (i use a 10 and a 20 on my reef tank, but i have over 300gal of water and tons of corals.)
what size tank are you needing it for?

As mentioned welding, fire extinguisher services, paint ball service stations, brewery supply stores, and some aquarium stores will all refill CO2. Just make sure it is a clean source on some occasions you come across accounts of dirty CO2 (oils).

How experienced are you with planted aquariums? Regulator, solenoid, controller, reactor or diffusor, bubble counter, etc…. Easy to end up with dead fish or tank full of algae.

I was hoping to find someone who had one used. I have been acquiring the needed equipment and it isn’t cheap to have a high tech tank.

I have had aquariums without plants for years and want to try plants. I have a regulator that has a bubble counter with a solenoid to control pH. I have been working with a guy that is helping me. I know that a nice planted tank is more difficult than plastic but I will do whatever it takes to achieve a nice planted tank. It sounds like you know a thing or two about planted tanks???

Lots of people sell kegorators with co2 tanks cheap on craigslist.

I bought a steel tank empty and took it to a welding store and they swapped it out for an aluminum one free of charge. (Not many places fill in front of you around here)

Good luck with the planted tank.

With some fertilizers(N,P,K,nitrate,phosphate,potassium),trace element,light,and weekly water change you can easily have decent planted tank,and once you have it well balanced you’ll never go back to fake plastic plants.
I used to get my co2 tanks from a local fire extinguisher place,fertilizers from Homegrown Hydroponics store,lights from AH supply

You already have a regulator/bubble counter,so it makes sense to buy a co2 tank but if you didn’t ,you could have gone low tech with co2 by mixing sugar and yeast.
This freshwater fishkeeping is a very expensive hobby just like woodworking ,so be prepared.

Go to a beer brewing store. They’ll hook you up.

Either rent a tank from any of the new places or buy new. Used are fine but I figure the cost of having them tested puts you at a new one. I could be wrong but I think they are to be pressure checked and stamped/certified every 5 years.

I have kept tanks for as long as I remember and some of my first tanks 30 something years ago as a kid were actually planted tanks. I took plants from the local creek that I liked and had them in my tank with a bucket of creek bank as my soil. Makes me chuckle when I see all the talk about mineralized soils, dirt capped substrate, Walstead tanks. Most of my tanks have been low tech and even now my only planted tank is low tech/low maintenance.

Buy a new one from a gas supply house. That way you know it is pressure tested and the valve is good. It is a one time purchase fee instead of a rental payment on a regular basis. Then you can go back there to have it filled and then have the valve and tank tested on a regular basis. Also buy a good regulator with a pressure relief valve, and store the tank and regulator secured in an upright position. Even though CO2 is relatively inert, it will purge the oxygen from an enclosed area if leaking or the pressure device diaphragm ruptures. Also high pressure gas cylinders are like an unguided missile should the valve be broken off due to dropping etc. As was mentioned, a 20lb tank is pretty large for residential use. I would look for a 2.5 or 5lb tank.
