help on CO2

Hi,

I've tried to produce A C02 kit.

After ahow long should I see bubbles coming out of the airstone.
I've had it in 4 hours and nothing comes out.

Could it be yeast not being enough?

Any advice would be appreciated.

what was your recipe? four hours may not be long enough, i'd wait a couple
days. are there any leaks in your setup? W.

Most likely problem is leaks.
Second most likely is bad yeast or too hot water.

To check for leaks submerge the entire generator under water and wait a long
time to see if any bubble appears. i found aquarium silicone and hot glue
were both bad, Liquid Nails works but only use on the outsed of the cap, it
smells like it would be bad for fish. Dry the top after you peel off the old
glues and then clean with alcohol. I've used Liquid Nails with a unit in
use, and the stuff dries even while bubbles try to come out of it. I found
it in my garage, and in Home Depot with caulks. It is a clear caulk-like
nail substitute.

Check your yeast first by looking at the date on the package. Then proof the
yeast (just like for baking), take a cup of mildly warm water and add the
1/4 teaspoon of yeast and a pinch of sugar. Wait as the yeast dissolves and
look for a fine foam to begin. Just a bit. Then you know it is good, pour
that into the generator bottle.

Last, be sure that if you used a check valve that it is in the correct
direction, take it out, blow through it to be certain.

And really last, if you have a bubble counter after the generator, which is
highly recommended for several reasons, it is a source of that many more
sites for leaks.

I found using home winemaking yeast produces better results than using
baking yeast, it last longer and you can buy a tub for not very much
at all.

I also make wine and was tempted to put a gallon carboy on top ot the
tank but thought it might be a bit heavy for the lid! and it might
produce too much CO2.

Hi,
It has been some times since i last used DIY CO2 (Swithed to canister as
i find it too troublesome to whip up the mixture) so i might be wrong.
CO2 may take as long as half a day before u see bubbles coming out,
depending on your mixture. Try to check for leaks by placing soapy water
around the joints if bubbles still did not appear. DIY CO2 has very low
pressure so any loss would be significant. Anyway, i remember my
airstone disintegrated into bits after a few weeks due to the CO2 and it
made a mess of my tank. Using a flipper will be a much better idea for
DIY CO2.

Some Links from AQ forum, a great planted tank forum which i visit
regularly, on DIY CO2:

Hope it helps you .....

You may need to wait a little more, if it doesn't start within 6-12
hours there's something wrong. It could be a leak or something with
the mixture. Here's another link that may be of interest to you:
