Co2... Help!!!
Hi guys I have a 1o gallon nano that I am setting up as some of you may know and I am setting up a DIY Co2 and have a 2 liter bottle ready for a yeast culture and have a air stone for a diffuser. Straight up do I need a regulator for the Co2. Thanks for all the help and post fast please.

For DIY CO2, I don't think you are going to find a regulator that works with such low pressure. You will probably want to invest in a bubble counter. I defer to more CO2 system-knowledgeable folks here!

Okay I might do that.

You may want to visit the planted tank forum:

Many of them are really into the CO2 and have a lot of resources posted.

Funny you should say that I am a member of them so I also have a thread going on there to.

I don't quiet see the reason for CO2 on a 1 gallon. Just be aware your parameters are really going to be a rollercoaster, especially with 2 bottles. There are no regulators for DIY yeast.

my bad 10 gallon

ahhh lol. I totally flew over the 'o' when I read it the first time. I wouldn't get a bubble counter. A drop checker would be better. Even with pressurized a bubble counter is suggested, but not a requirement. It just gives you a visual measure of CO2. The proper BPS varies from tank to tank, especially if you have poor diffusion. A drop checker though gives you an accurate measure of CO2 in the tank water, but only if properly setup.

my main qeustionthough is do I need something that regulates how much goes in, I want fish in the tank. And how much do drop checkers cost.

The drop checkers are not expensive $13 CO2 Indicator | CO2 System Components | CO2 Equipment | Aquarium -
I made my own bubble counter. Once I got the bubble count correct with the drop checker, I took the checker out.
As far as a regulator goes.... I put a T in the line going to the bubble counter, on the open end, I put a standard inline valve. if the bubble count was too high, I opened the valve and let some bleed off. It seems like a waste, but the container the yeast is in is not designed to hold pressure, so the only way to decrease the CO2 going into the tank it is to vent it.
