I will have to look into the co2 I know nothing about it ...really appreciate the information...do you use tubs for your rats?

If you go to the DIY section of the forums, there are a lot of people who have made CO2 chambers. It's all good info. As for my rats, I use cement mixing tubs from Lowes and have the rats in a rack system. It works out really well.
