What the heck is this white stuff??????

There is a white sludge building up under my bubble ladder, right where the c02 bubbles come out. I'm using a sugar and yeast setup to diliver c02. I'm affraid that this white stuff is toxic. I thought it might be the sugar and yeast sollution comming out, but I havent touched the pop bottels for 2 days and the sludg keeps building up. No matter how much I try to clean it, it just keep building up? What should I do?

It's a build up from the CO2 bubbles I believe. A little bit of your yeast, sugar, baking soda and H2O (ingredients from your DIY CO2) is scrubbed off of the surface of each bubble and deposited where it comes out. I just clean it off every once and a while with a small brush or even a pipe cleaner. If too much builds up, the bubbles may not 'roll up' the ladder correctly and just float to the surface. I don't think that you would see this same deposit if you were using a tank of CO2 like you see with DIY CO2.

ya, thats exactly whats happining. There is such a build up of the white stuff that the c02 bubbles wont flow up the ladder. I have to clean it off every day to make sure the c02 bubbles go where they are supposed to. I guess this white stuff isnt toxic, so I won't worrie about it as much. Thanks for the responce..

Gosh, I don't have to clean my ladders but every once and a while. That's usually about every other refill. Do you have just one ladder on your 75g?

ya, I'm just using one ladder. It's hooked up with two, 2 liter jugs, and a gang valve.

I'm not sure why its building up so fast in my ladder? Mabey its the ingrediance I use in the mix?. I've never heard of anyone else having this problem. It's so bad that I might have to dissisemble it because I'm affraid that it will afect my watter.

For the yeast suggar solution I mix...

- 1 tsp yeast
- 1.5 cups of sugar
- 1 tsp baking soda

add a gas separator between the CO2 generator and the bubble ladder. I use a 20oz soda bottle, 2/3's full of water. run the CO2 into the bottle, and use rigid airline that extends down into the water. Then have a little piece of tubing that vents the CO2 out of the top, and run airline to the bubble ladder.
That should totally eliminate the fluffy, snot-like white stuff, which is indeed some kind of fungal residue from the yeast.
