sticky if you can
i got this while i was browsing through ebay to look for some glass co2 diffusers so i looked at this one, and when i scrolled down i saw some instructions on how to make some DIY co2 yeast bottles. i think this information would be usefull for others. so... here u go, my diy co2 project hasnt started yet, by the way in malaysia it is hard to find 64 oz/ 2litre coke bottles, ( in my house no one drinks juice !!! ) so i will be using a 1.5 litre bottle.. here are the instructions,
items needed :
64oz bottle/2litre bottle.
2 cups of sugar
1 teaspoon of active dry yeast
lukewarm water to fill it to the rectangular part ( look at the picture )
the tubing trough the cap : the ebay guy punched a small hole with a nail and used a pair or pliers to pull the tube through the little hole, this makes a perfect seal without using glue or stuff...
pour 2 cups of sugar into the bottle
fill it with luke warm water ( again, look at the picture )
add 1 teaspoon of yeast
replace lid and tighten as good as possible
place the diffuser inside the tank
wait 3-4 hours,

try at your own risk. if there are any blockage in the airline, the bottle may burst, the ending result is, sweet smelling messs.
if i were you i would use a checkvalve to prevent back siphoning
comments are welcomed
if you dont have a check valve,
you can make your own.
using smaller bottles
as the water goes backward into your co2 bottles, it enters the smaller bottle instead of messing up the co2 stuff. and most of the times, the mixture will bubble up and get into the tank. but this mechanisme has stopped stuff from getting into my tank. its best if you tape them together.
another safety system is
a pressure safety valve. this diy pressure realese valve is a simple mechanism. they used a T connector... and a rubber cap. the bottom of the t connector was sand papered, not too much not too little. if it is too much the rubber cap will pop out easily under pressure. but if its is sandpapered too little, the rubber cap will not come off. so to make this thing right, the sandpapering has to be precise...
hope this help.
ps: ive been trough many of my own diy co2 bottles.
they work better than those that require a refil pack
like hagen and red sea
