If you shake the bottle you WILL be a pressure build up Quote Link to comment Share on other sites More sharing options...
SamH Posted October 19, 2009 Author Report Share Posted October 19, 2009 I shake up all my bottles, it'll leak before it explodes because: 1. The gas escapes out the end of an unblocked airline tube 2. The hot glue around the top leaks CO2, especially if the airline tube is blocked (It would be cool if it did blow though) Quote Link to comment Share on other sites More sharing options...
N1CK Posted October 19, 2009 Report Share Posted October 19, 2009 How would it be cool your house would smell of smelly DIY CO2 stuff :lol: Quote Link to comment Share on other sites More sharing options...
SamH Posted October 19, 2009 Author Report Share Posted October 19, 2009 How would it be cool your house would smell of smelly DIY CO2 stuff :lol: BOOM! That's how it'd be cool. Then I'd just shut the door and let the fumes take me away Quote Link to comment Share on other sites More sharing options...

SamH Posted October 19, 2009 Author Report Share Posted October 19, 2009 As high as you like, as long as no water is or is close to touching the airline. Quote Link to comment Share on other sites More sharing options...

Jennifer Posted October 19, 2009 Report Share Posted October 19, 2009 I have been using DIY Co2 for a few months and just recently come up with a really good system that works a treat for me. I use a 2.4L bottle and add 2 cups fine sugar, 1 heaped teaspoon fresh yeast (not old yeast and not the bread maker type yeast), a pinch of baking soda and a smear of marmite. I add warm (35 degrees) water to fill the bottle up to about 3/4 full. Then I shake over the sink to dissolve. I then place it in the cabinet next to my warm canister filter and forget about it for 2 to 3 weeks. I have airlines that go to bell diffusors or frits so there is nothing blocking the line - they bubble like mad and all the plants have O2 bubbles within hours!

SamH Posted March 11, 2010 Author Report Share Posted March 11, 2010 Old thread but we don't need another DIY CO2 thread :roll: I just need some advise. Instead of buying a gang valve and waiting for it to be shipped to me, will this work just as well? Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted March 11, 2010 Report Share Posted March 11, 2010 can you see any reason for it not to work? Quote Link to comment Share on other sites More sharing options...
SamH Posted March 11, 2010 Author Report Share Posted March 11, 2010 can you see any reason for it not to work? No, but I tend to overlook certain things. When I come up with something I seem to miss the flaws :oops: Quote Link to comment Share on other sites More sharing options...
