Which Co2 DIY system,

I just threw a Red Sea in the trash the other day.

Bought it a long time ago. It sat around for about a year. Fired it up. Didn't notice much for any bubbles. Re-done the mixture again. Again nothing. Made a 2L bottle. With in 12 hrs, alot of bubbles.

I saw someone selling the Hagen type in our classifieds the other day, for $20.
 
lol I wasn't recommending either one. But figured I'd let you know there was a cheap one for sale, if you were going to use one.
 
If i get that glass diffuser, do i just attatch the end of it to my air tubing connecting to the 2l bottle? And whats a gas seperator?

Yes

And whats a gas seperator?

Can be a 12oz soda bottle after the 2L.

It will trap any moisture(yeast) that might come from the 2L.

Also, get a check valve to use in line. Between the seperator and aquarium.
