Re: DIY CO2 System I found it effective for a while and it turned out to be a bigger pain in the a$$ than anything. The violent swings in co2 levels caused incredible amounts of beard algae that I couldn't eliminate. So I upgraded to a pressurized system and haven't had anything but great results. Id say use only Excel for now and don't even bother with the DIY. Upgrade to pressurized if you can. I really wish I would have done it from the start. But I wouldn't evwn bother honestly |
