    I set up a diy CO2 just 2 days ago. I attached an airstone to the end of the airtube into my planted tank. But I notice this morning something is forming on the airstone and not sure what it's. As I was in a hurry to go to work I just took a picture of it. Can someone tell me what is it forming on the airstone? Thanks in advance..

    Looks like some fungus growth, I would have it clean and soak in a dilute bleach solution, remember to wash off all traces of bleach before putting back into the tank.
    ...I love rubies too ...

    Don't need to worry... If your tank has oto or something, the fungus will be eaten away.
    Or it will automatically disappear after a week or so...

    That is a form of fungal growth. You speak of DIY CO2 which is a mini yeast production factory. It happens all the time and usually will not do any harm, some fish even will delightly eat it. To avoid any more growing and worry you (or even worse clog the stone), it is best to add a bubble counter between the DIY bottle and the stone. This acts as a catching media, not allowing/reducing greatly any yeast that might escape trough the tubing.

    best is to use a ladder diffiusor. using airstone will clog ur airstone with few days. it caused by the yeast reacting in ur DIY container and therefore the co2 produce from the bottle to the airstone will clog within 1 hr.

    I'm having this problem again. Is it possible it's becos I mixed the wrong proportion in my DIY CO2 container? or is it the yeast I 'm using. What I did was I mixed water with sugar, then add some soda powder or something...then last add in the yeast.

    Where did I go wrong?

    ur mixture sounds ok to me. that type of fungus is common on airstones, i would suggest u use other forms of diffusing device. if not u will have clear ur clogged airstones often.

    Use a bubble counter (make one from household items if you want it cheap). The water in counter acts as a catching media, there should be no or greatly reduced fungal growth if you do so. No matter what you use; airstone, diffuser, even a reactor, the fungal growth will be there by the outlet if you let it (CO2 line from DIY bottle) into the tank without screening it first.

    Your mixture is fine, as you can see it produces CO2 and your yeast is multiplying well (even to the airstone).

    If it's harmless to my planted tank and guppies...I think I'll just let it be for the moment. Learning so much here and there is more to learn...thanks guys
