I checked out Daves, page but, I thought someone would get mad if we talked out of subject here. I only run one of my house tanks on DIY yeast. It works fine for me. I try the 10% water change every week and I change DIY yeast every other week whether it needs it or not. It's become quite simple for me. But, if I were not to busy with all these breeding tanks I'd get more serious about the Co2 and go with Daves stuff. He seems to have good advice and prices too.
