Does anyone get CO2 bubbles collecting on the surface of the water after
they are spit out of a powerhead?

pH level change with co2 injection, but the amount that it changes depends
alot on the co2 levels in combination with the carbonate hardness of the
water... It varies depending on the water quality. my pH has gone done by
about .2 since i have started using my DIY method.. I might add though
that
you should pay attention to the co2 levels in the tank...

I found out a few weeks ago that if you dont have a way to regulate the
co2,
you start ****ing the fish off. I tested my co2 levels and found that i
was
in excess of about 50ppm (wayyyyy to much). What I started doing to
regulate
it is put the powerhead that distributes the co2 bubbles on a timer with
my
lights, and this has helped dramatically. I run a plastic thick tube up
to
my powerhead form below, and I put the co2 line up into that tube (so the
tubing catches and contains the bubbles.) when the powerhead is on, it
disperses very fine bubbles into the water (allowing for better
diffusion),
when it is off (at night) the co2 is contained in the tube and really goes
nowhere... This has helped me stabilize the co2 influx into my tank
because
i can simply adjust the timing on the powerhead for shorter intervals if
there is too much co2.

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?

How big is your tank?

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
