OK. I was basing the yeast quantity from the mixture Jason recommended in
the thread "DIY CO2 Instructions" for a 2 L bottle. Maybe this was a little
too much. I'll dump the mixtures in the morning and remake them with only
1/2 tspn of yeast. Am I ok with the 2 cups of sugar?

The bubbles were coming from the Eheim outlet after I stuck the airline into
the intake. However, my Amazon Swords do pearl throughout the day. Maybe I
can get by with one bottle and use the other one as a rotater when a new
mixture needs to be made.

The PH always stays at 7.5. It has not changed since the mixtures have been
going, but they have only been going for 8 hours or so. Since I removed the
airline tube from the filter intake, the bubbles probably aren't disolving
in the water as good right now.

thanks.

Whoa, ease up on the yeast, using too much initially will cause the
mixture
to expire much sooner. If you're putting it into the eheim intake I think
you only need 1 bubble about every second for a tank your size. 1/4 -1/2
a
teaspoon is sufficient to get the reaction started. I've got 1 bubble per
3
seconds for my 150L(~38G) aquarium. So if you're going to use two CO2
bottles for the 75G tank try to cut back on bubble rate. Are the bubbles
in
your tank coming from the plants or from the outake of the filter? Have
you
measured your Ph before injecting and now?

Hi.

http://www.geocities.com/slimflem/co2/

Here are some pics of my DIY CO2 system I made today. These wine
bottles
are about 3 L. I used 2 cups of sugar, 1 teaspoon of yeast, and 1/2
teaspon
of baking soda. After the bottles have been sitting for about 1.5
hours,
I
am already getting bubbles from the airline...about 1 per second. I
thought
it took at least overnight for the yeast to activate. Could this be
CO2
this early on? Could it be due to the fact that the yeast was room
temperature when I made the mix? Or is this just air being pushed
out
of
the bottles and not really CO2 yet?

Also, from looking at the picture, tube_in_filter.jpg, does this
look
ok
for
injecting it into my tank?

Thanks,
Jesse
