will the diy c02 project cover my tank?

[GIMojo]

is one 2 litre bottle enough to cover all the plants in my 70-80 gallon tank or do i need 2 bottles?

also how do you get the c02 dissolved in the water exactly? i read that you can put the c02 end into the intake of the canister filter. does this really work? does anybody do this?

yeh, so screw buying a c02 bubble maker from the lfs, im going cheap and making my own. doesnt look very hard. also ill probably have to get greenmagi's aim or something to guild me through building the ballast thing for my light

i think I read that 2lr will cover 30 gallons, so I'd get 2 or 3 bottles.

presurized is actually the best option with a tank over 55 gallons.. but we have a user that has had some sucess in a 90 gallon with 5liter garden sprayers for generators.. I think he had 4 of them online last time I checked.. Ill bring your post to his attention.. good luck..
