    I have this guy here and have had problems mixing up the juice the last 2 times.

    First time: Was a few months back when I still had plants. I thought that I may have had a siphon go back into the CO[SUB]2[/SUB] reactor right away and spoil the mix. Just kind of blew it off for a while.

    Second time: Mixed it yesterday according to instructions. No siphon happened and no reaction either. It doesn't say to mix the ingredients after you are prompted to add the water and replace the lid. Seems like it should be mixed?

    Hi Casey - did some research and cut and paste the below for your information
    credit to George Farmer for the user instructions based on his experience below

    Here's a basic guide to using the popular Nutrafin yeast-based CO2 units, based on my own experience.

    1. Fill canister with regular granulated sugar to the first line.

    2. Add 1/2 teaspoon of dried yeast (available from supermarket).

    3. No need for "Stabiliser" unless you have v. soft tap water.

    4. Top up to second line with tepid (approx 30C) tap water.

    5. Stir.

    6. Fix lid tightly.

    7. Attach tubing tightly.

    8. Watch the bubbles appear after 10 to 30 minutes.

    Ambient temp. affects bubble rate, cold = less output, warm = more output.

    More yeast = more CO2 for shorter time.
    Less yeast = less CO2 for longer time.

    1 teaspoon of yeast will give you around 30 bubbles per min. for about 7 days. This should be good for up to a 100 l. / 30 gal. tank.

    Aim for 30ppm CO2. Change mixture regularly to avoid unstable/low CO2, this causes algae. Test for CO2 using pH and KH kits and this table - http://www.tropica.c...q...stic&id=445

    Clean ladders may clog bubbles up for a while. The bubbles will run up smooth after a few hours or so.

    Use multiple units for larger tanks. Change mixtures alternately for stable CO2.

    Enjoy your plants!

    It's probably just yeast and some kind of sugar.

    With bakers yeast its important to hit 100 degrees f to activate it.

    Thanks sostoudt, I usually just use lukewarm tap but maybe I need to use my hanna checker. I was of the understanding that if it is too hot, it can cause issues. Maybe I'm being too careful...

    Good info, Steve... I did use the stabilizer packet and have very hard water. So, I am going to the pet store and buying some re-fill packets for the reactor and trying again. This time without the stabilizer and warmer water.

    100-105 degrees to activate, 110-115 kills. in the majority of baking and drinking yeasts. If you leave the mixture out in a glass for about 20 minutes you should see some bubbles, that are produced from the co2 reaction. my advice is make sure the yeast is working before setting up your canister.

    Honestly for all the time and effort your going to put into a co2 reactor you should just look into pressurized. There is no consistency w a reactor. This is what I bought after looking into both options:

    Co2 needle valve w gauges and electric solenoid: 100.00$
    Co2 bottle 20oz walmart: 7$ for exchange as well or you can have it filled

    That's all folks total 107$ the bottle lasts about 1 mo, you can get a 5lb bottle for 100$ that lasts 1 yr on a 55 gal.

    I run mine on a timer w the lights. It runs into a sediment filter (50$) that I drilled and tapped. It completely dissolves co2 into the water column and flows in with return water from the canister.

    Hope this helps

    Eh, a little too involved for my little 7 gallon.

    On a side note: I broke out the hanna checker and brought my water temp up to 106 deg and it kicked off right away.

    Next thing to figure out is the bubble rate and length of time it spends on the ladder.

    Have a few of that eaxt model ..

    Sugar to the mark on the inside bottom, 1/2 teaspoon bakers yeast (local food store off the shelf) and 1/2 teaspoon baking soda..

    Fill the water to the upper mark stir and put the lid on..

    That's it..

    Save your money and do not buy the 'refill packs' they sell at the LFS ..
