Does anybody who use diy co2...

[revengeishere]

use flour instead? Well, I'm gonna try it, and it just seems logical that flour(refined) is made up of simple straches anyway, and has loads more protein, and other nutrients than just sugar, thus, the yeast last longer.

There are also other variations like adding some sugar to help jumpstart the yeast, since it takes longer for the starch form the flour to be available to the yeast.

If you have any experience with this, please do post here.

Thank you.

Anyone thought of making homebrew and rigging the output tubing onto a airstone in the tank....mmmmmmm hombrew ........mmmmmmmmmm........co2 generator....

update, its working !

well, I dont really know if it is working because im using two bottles, one fore flour and the other sugar, I'll try an all flour next week...

great ideas but will the air giong in your tank from these contaminate you tank?
i had a big prob. when my elect went out with the hurricane last week and my hubby was the brains of this idea. he started up the van pluged in the portable tire pumper. ran a tube from the tank to the van out the door and to the pump. we had to put a few holes in the line becuse there was to much air but it worked wonderfull for 8 hours last time we had power failer we lost 4 fish and with saltwater that ment about $200 worth of fish. any other ideas let me know we have power failure sometimes around here.

sorry i heard about your fish, I have looked at getting a UPS? there is calualtion you can use to calculate the UPs reqiurements - they can be purchased from any good computer store - or online

I would get one if you have power failure

why not just use a battery operated air pump, it is ideal for a power outage.

just buy a generator? you can get small 700watt output models here in the UK pretty cheap. i think they run for 6 hours on a litre of fuel...

i want to make a DIY reactor. If anyone has a good setup and/or instructions, please let me know. I made a small one last night to see if it would work. It did and I produced about a pint worth ( displaced water) of CO2. My setup was simple- used a glass bottle and cap, some tubing, and an upside down tupperware piece (square). sumberged the tupperware upside down and displaced water from it with the incoming CO2. I used sugar, water, and the yeast. How long does yeast produce CO2? what is the best solution to use? What is this about flour?

For my DIY CO2 reactor I have a 2000 ml Erlenmeyer flask with a rubber stopper. I put a hole through the rubber stopper just a bit smaller than a hard plastic elbow bend tube (a little bigger in diameter than aquarium tubing). I put one end of the plastic tube through the hole and just below the bottom of the stopper and then connected some of the more rubbery aquarium tube over the end of the elbow bend. Then I attached an airstone to the end of the tube, put it into a 50ml beaker and put that into the top of my aquaclear filter with the mouth of the beaker facing the part where the water comes into the filter area. The water rinses through the beaker so that the CO2 dissolves in the water.

For my mixture I use about 2 teaspoons of Baker's yeast : 2cups sugar: 2.33 L water.

When I reread this it seems hard to visualize, but I hope it helps.


(I am in Molecular Biology, so the science equipement can be bought cheap. I am sure a pop bottle and another small container would suit nicely.)


I am in the process of buying a magnetic stir plate/ hot plate to keep the mixture at an even temp.
