Basic components of a pressurized CO2 system:
Regulators: there are many brands and components to a regulator. I recommend a regulator with a solenoid, and a bubble counter. The solenoid allows you easily control your CO2 using an inexpensive timer, or an expensive pH controller. A bubble counter is a simple way to guess how much CO2 gas is in your aquarium. You may want to shoot for 3-4 bubbles per second depending on lighting and plants. I personally recommend the Milwaukee regulator and have used one reliably for years.
CO2 tank: A 10 lb tank might last you 3-4 months before needing refilled. You can get a 20lb but they are huge and ridiculously heavy. On my 29gal, a 10lb tank lasts 6 months. Tanks ship empty and you have to find a local source to fill it with CO2. Try welding supply or home brew beer supply. You will need disposable seals too.
Diffuser: This is where you have a lot of options. Ceramic diffusers are effective on small-medium tanks. CO2 reactors and DYI options using your filtration system are effective on a large size tank. I can't give any recommendations on these 2 options, sorry, hopefully someone will chime in.
Other important equipment includes CO2-safe tubing, a drop checker, maybe a brass check valve if needed, and the aforementioned timer. Hit me up if you would like recommendations for these items.
This is what I have been using for a while. It works great and is a pretty good price.
I have no experience with these...but look: Just read the reviews before you buy.
