i just made one of those diy co2 makeing thingys it was goin fine with little bubbles coming out but i just moves the bottle a little and this creamy fog just went out the bubble creating thingy eeek :dive:
 
help..
 
Do you not have a check valve between the bottle and the diffuser?

Never run a DIY without one. They're cheap, only a couple of bucks, and keep you from getting that guck in your tank.

Take it off until you get a check valve.

is the gunck bad for my tank?
 
bad

yes, if yeasty water got into the tank, that is not good. You may want to do some water changes to remove any yeast water, a lot is a big problem, a little may not be.

More important, why did any get into the fish tank? Was there water in the gas line? -- next time shake that water back into the generator so it does not travel to the fish tank. Did the generator get shaken? -- do not shake the generator, you don't want yeast water in the lines. Did the generator foam up? -- leave a large gap of 2 or 3 or 4 inches between the water surface and the exit gas line so foam does not get in the line, and consider installing a bubble counter that can scrub the gas of any yeast so that none gets into the fish tank.
 
dam.. better change the water fast .. it happened 2 days ago oh yea and i noticed the bubble making thingy *i dont know what its called* had got a like white coating i thikn its mold but im just a newbie

Further to that, I was just told to use a wash bottle instead of a check valve, because they can fail.

Now to find out what a wash bottle is and how to make one :)

I suspect they mean a bubble counter which will act as a scrubber as the gas goes through the water and up the exit line to the fish tank. Just look up directions for a bubble counter... I used a small soda bottle, 2 holes through the top, the line that comes from the generator goes about 3 inches into the bottle and that is about 1 inch below the water level in that bottle. The exit line is about 1 inch above the water level. Gas comes in, bubbles through the water and yeast is cleaned out to some extent, then the gas exits and goes to the fish tank. When you change the mix in the generator, dump the water in the bubble counter as well, it will smell a bit like the generator water, but less.

I never could rely on the check valves, the plastic ones always got wet somehow or just leaked after awhile, I guess the acid from CO2 + water.
 
generator - has the yeast mix inside
bubble counter - has water and no yeast mix
reactor - mixes CO2 in tank water, may be internal or external, powered by water flow from pump or filter
diffuser - mixes CO2 in tank water, internal, no power, just very small bubbles and possibly a long travel path in spiral or ladder form

Start learning the lingo, it makes diagnosing things much easier!

The white snotty looking stuff is from the generator, not harmful but will make the bubbles go off track on a ladder diffuser or can plug up airstone type diffusers. A bubble counter can scrub this bit of yeast mix from the gas and keep those things cleaner, as well as allowing you to count bubbles.

If you have a Hagen CO2 system, don't bother with the bubble counter, just rinse the lid and the airline in very hot water each time you change the mix and do not shake the generator, either stir or don't stir, the yeast will mix itself anyhow.
