any insight on co2 generators? pros cons...
I've done both pressurized and DIY. I would highly recommend a pressurized setup if you can afford it.
DIY (Yeast + sugar):
Pros - Very cheap
Cons - Inconsistant bubble production; must replace mixture every few weeks; can be prone to leaks over time
Pressurized:
Pros - Consistant bubble production; can last for many months or even a year, depending on bubble rate and tank size
Cons - Initially expensive to set up ($200 or so)
Unless cost is a BIG issue, I highly recommend pressurized right from the get go. It is a decision you won't regret.
Plus, if you salt tank picks up, you can split your line and run a calcium reactor too.
I`m with the others,pressurized is the only way to go with a tank that size ( 90 Glns.), DIY is do able but will require a lot of attention .
