I don't know any links to DIY sugar Co2 systems, but I do know Jungle makes a reasonable priced fermentation unit that would do a 30 br. It's like $40.00 tops for the system and if you're not all that great with DIY like me it's well worth it. A pressurized CO2 system is not something to play around with, my friend made one an ended up losing an entire tank of fish due to some stupid mistake. Also, I have a 30 breeder planed tank, and I use 2 separate 65w compact flourescent fixtures, it's a bit much but I'm happy with it. You could get away with one, but the tank is so big you're gonna have dark edges because the light wont cover that much of the tank. Anyway, good luck on your tank and have fun.
