DIY Co2?

[blazeyreef]

I have been reading everyone about this, and trying to figure out HOW to do it..I have been looking on google and still cant figure it out...so could someone please explain it to me

very simple. get a 2 litre bottle. drill a hole in the cap the size of the co2 tubing. push it in about 1/2" then silicone it air tight. run that line into your tank into any kind of diffuser u want. most people run it into the intake of the filter. thats it. besides the mixture which is like this...

1. mix 2 cups of sugar into some water and add it to the bottle.
2. mix 1/4 to 1/2 tbs of yeast in some water to get it going then add it to the bottle.
3. fill the rest of the bottle with water to the beginning of the neck.

and your done lol. get it?

Here's a really detailed article with some great pics. Should help to clarify things.

As far as the cap is concerned, I have always just drilled the hole smaller then the air tubing and then sliced the air tubing at an angle and pulled it thru the hole with pliers. Purfect seal everytime. no need for sealent or bulkheads.

yes i do drill mine a size smaller but after a while the tubing shrinks a bit and the seal isnt quite as good. thats why i out abit of silicone around it. just an extra percausion.

good point, seems that new a piece a tubing would also would also be just as good. sorry, back on topic.

I use something a little different that I have found makes a seal so tight it is hard to remove. If you can find those little adjustable flow rate blue connectors in your LFS, they have a small piece that you can remove. Once removed, and with a little force, you can put the small piece in the end of tubing after inserting through the hole and push the connector through the hole. Hvae never had a leak by doing this. You can also use a T connector or anything else that is about the same size and it works jst as well.

As for the mixture, wine yeast seems to be the best from what I have read and I plant to switch to it soon.

? what do you mean? the bottle DOES push the stuff out itself.

the yeast eats the sugar and produces CO2 (fermentation) and when enough pressure builds up, it goes into your tank.

The link that Purrbox listed explains a lot.

lol i guess without actually seeing it in action it is hard to explain. it is so simple that it seems hard. since the tubing is sealed in the cap there is only one place for the gas to go... through the tubing. it will continue through the tubing untill it can get out which i what u want to happen. the end of the tubing in your water goes into your siffuser. it can be a powered one like the redsea kit or as simple as the hagen bubble ladder. or like i do just put it into the intake of your filter. this way the filter sucks the bubble up and the impellar breaks it up and it goes into the water. thats it. so unless the tubing is blocked and the co2 cant escape that way(which will casue it to explode, watch out for that lol) all u have to do is make your mixture and watch the bubbls flow. u can see the gas moving down the line in the water after u do the mix. if u shake the bottle it will move faster(since u are casue the mixture to kinda go into overdrive)
