Re: [APD] c02 in a 5.5
You have lots of simple choices here. But essentially you
want to make the yeast less happy or waste off some of the
A few choices are,
insert a tee and bleed off some of the CO2 into any other
container of water or anything that offers some
How are you injecting the CO2? With a stone? Then raise the
stone closer to the water surface. With a ladder? Shorten
the ladder. Raising ladder and shortening the stone is
generally more difficult ;-)
You can always add some turbulence -- add a powerhead,
install a spray bar -- make a splash in your aquatic
Install a wet-dry filter, you can cut your CO2 retention in
Put a pinhole in the CO2 tube in the aquarium just below
the water surface.
If your room is relatively cool (below 70 degrees), you can
get a yeast that is active at higher temperatures but not
so much at the ambient temperatures in your fish room,
house, etc. A nice dry yeast that prefers temps of 70F or
above. Use this at 60F and it will "cook" slowly and not
stop until the alcohol is 15-20%, depending on the specific
There are a lot of yeasties to choose from here:
And you get info on the various strains at whitelabs.com Of
course, once you get a bottle started, you can keep the
culture going for ages without needing to buy more yeast.
I think you can add some extra baking soda -- the yeast
prefer acidic environments of around pH 3-5.

The AGA's Sixth Annual International Aquascaping Contest is open!
Enter more than once. Enter entirely electronically!
So, get some fresh alkalines for the camera, clean the glass front, back and sides, remove the filter tubes and burping clam, and start snapping the shutter.
Not ready for picture taking yet? There's still plenty of time for planning, planting, pruning before the Septbember 15, 2005, closing date for entries.
