CO2 system set up.

[squirt_12]

ok well i didn't know where to put this under but....i am thinking of setting up (making my own co2 system) and well i wanted to know if the yeast that comes ina package and the brand name is "Fleischmann's" well i was wondering if that kind of yeast wouls work??
Also i want to know....if something goes wrong (for some reason) would the mixture hurt my fish in anyway????
Also my tank is a 33g. THanks!!!!!


P.S.
How have your systems worked??? (if you have made your own)

EDIT- Also on the ingrediants for the yeast package they are: Yeast and sorbitan monostearate.
So would they be alright?

Killed 10 of mine over nite. Make sure the line that goes into the bottle comes above the liquid. I have mine cut now to about 1 inch with the liquid at 3 inches from the top. Then I darned near caused another problem by having my bubbler too near the filter. I think the filter sucked the liquid out at too rate a speed and I had slime city in the tank by morning and gasping fish.

[squirt_12]

ooooo......that right there makes me no longer wanting to make this.

[squirt_12]

so yeah i don't think that i am going to try this because it sounds really risky and i don't want to loose any of my fish.

[cocoa_pleco]

lol, thats why i bought the nutrafin Co2 kit, i would screw up the DIY one

[squirt_12]

are those kits expensive???

[cocoa_pleco]

kinda, theyre usually 35$ for the whole kit (fermenting canister, bubble wall, yeast and activator for 2 rounds), but i got mine for 20$ on sale.

No they are like $30 but I think anyone will tell you that DIY is more efficient and really isn't that dangerous, as long as you only fill your bottle several inches from the top of the bottle. Also, what I do is I make my solution and don't put the cap on and let it sit overnight. This way if it does foam up way too much it will die down or you can just pour a little out. The only time it is really going to foam up is the first day when the reaction really takes place, after the first day it is going to settle down and be steady.

ok well i think now i might try and make one. But will the yeast that i described above work?????
Also on the pics on how to make one they have this little blue thing in the middle of the hose...now would i need one of those and what are they called?

[squirt_12]

ok well i stole this picture from Bill (thats who i think it was) and well the blue thing that is in the middle of the hose....do i nee one in order to make a co2 system?????

My Co2 system has worked great. It's been producing co2 for twelve days now. I haven't had any problems with the yeast/sugar water getting into my tank as i have a gas diffuser for that reason. As an added caution.

What you need are: 2 liter pop bottle, another bottle for the gas diffuser ( i used a 32 oz. gatorade bottle for the wide cap), a 20 oz. pop bottle, a pair of scissors, a hot glue gun, some air line tubing, and that little blue thing which is a flow regulator (only lets air flow one way), drill with bit smaller in diameter than the air line, suction cup.

You need to drill 1 hole in the cap of the 2 liter pop bottle. Drill two holes in the gatorade bottle cap. Drill one hole in the 20 oz. pop cap.These holes will be smaller than the diameter of the air line. Next cut the 20 oz pop bottle in half to make the bell where the Co2 will go. Next cut the airline into desired lengths. Then cut the ends of the lines at an angle about a 1/2" long. Now insert the angled end of the tube into the pop cap and pull. Cut of the angled part. I cut this one about 1/2 inch long. Use the hot glue on the outside of the pop cap to seal the hole and hold the air line in place. Cut this line in half and put the flow valve in. Take the other end of the air line and insert it into one of the holes in the gatorade cap and pull. Cut of angled part. I made this line about 3-4 inches long so it will be under the water level of this bottle. Now insert the other air line into the second hole of the gatorade cap and pull. Cut of angled part. I made this one about 1/2 inch long. Glue top of cap to seal holes and hold tubing. Insert the other end of this line into the 20 oz pop cap. Cut off angled part. I left about 1/2 inch long. I did not glue this one. Put caps on appropriate bottles. Cut hole in bell for the suction cup. Finished product will look similar to my pics.

Fill gatorade bottle with water until the one air line that comes from the yeast solution is under water. This serves as gas diffuser/ bubble counter.

The flow valve will keep any access water getting into the yeast solution which will make it bubble over.

Co2 recipie:
2 cups warm water
2 cups sugar
2 1/2 tsp yeast
1/2 cup hot water from tap

You need to put two cups warm water and two cups sugar into 2 liter bottle. I then shook this to mix. Add the yeast to the hot water and stir to rehydrate the yeast then pour into the sugar water. I then shook again to mix yeast and sugar water.

Wine yeasts work better, they can tolerate higher alcohol levels

The blue thing in the middle of the hose is just a check valve, it's so the water doesn't go back into the bottle and fill it up. You don't really need it, just make sure your DIY bottle is higher up than your tank.
