Ok. I'm a bit confused on how to set up CO2 and what I need to buy. I'm setting up a 40 gallon and want to use CO2 and may even consider it on my 10 gallon if my plants struggle. I tried to read through the stickies but got a bit lost. Advice and an explanation of what I need would be so helpful. Would like to keep the set up for the 40 under $250.

Welcome to the co2 game. I just got started with co2 myself. I would check out CO2Art's website Aquarium CO2 System Specialists | Diffusers, Regulators | CO2Art.co.uk. They have several all included set ups. Green Leaf Aquariums Green Leaf Aquariums is another site with full set ups. I would say that the amount of money you are willing to spend and space available will help guide you in your choices. There are nearly countless options out there, and a broad range of expense. Being my first time using co2, I went in the middle of the price spread. I have an Intense V3 paintball tank regulator with solenoid and Intense diffusers, cheap drop checkers,in line bubble counters with check valves, a cheap lamp timer and co2 tubing. If you study some of the set ups you will see all the individual parts that one needs. Then, you can shop around for the best price on the individual parts and maybe save some $. I have heard, and believe, that a regulator with a good needle valve will probably help make your co2 experience less frustrating. Hope this helps.

I broke it down like this:

1) CO2 source (Yeast vs. Compressed)
2) Regulator (Single vs dual stage), Many options
3) Solenoid (to turn the gas on and off), Many options
4) Needle valve (to adjust the amount of CO2 going to the tank), Many options
5) Bubble counter (to determine the amount of CO2 going to the tank), Many options
6) Tubing (To take the CO2 to your tank)
7) Check valve (To keep water from reverse siphoning into your CO2 equipment)
8) Method of diffusing CO2 (Reactor, ceramic diffuser, atomizer, bubble ladder etc.)
9) Method of determining amount of CO2 in the tank (Observing plants and critters, pH charts, drop checker, pH probe and monitor
10) Timer to turn the CO2 on and off.
11) All the connecting pieces (hose barbs etc.)

Where are your questions?

Thank you! It helps for sure. I'll check out the sites. The idea of building my own right now is a bit daunting but I think my hubby would enjoy that part. I feel like with a toddler, baby on the way, and working 3, 12 hour night shifts at the hospital in a row leaves my brain with no more space and myself with very little time to study how to make my own set up. :)

This helps a ton. I wasn't sure of all the parts I needed. How do I start with the determination of how much co2 my tank will initially need?

depends on how many plants and how fast they are sucking the CO2 out of the water column..

figuring out how much CO2 is in the tank is commonly done either by a CO2 drop checker:

Or testing pH drop (chemical or automatic.)

or the ratio of Kh to pH


drop checker and bubble counter it adj. is really the easiest..
If you screw up your fish wil be gasping for air at the surface..
Point is even w/ all the aids a bit of trial and error and observation is necessary..
