DIY Yeast method materials...

Do you think it's ok that the outlet of the co2 concoction gets piped into the inlet of an air pump? That's what I've just done today...can't find an easier way to get the co2 into the tank otherwise. Actually I've used two pieces of tubing out from the bottle and it rests underneath the air pump near the inlet, and I removed the air filter too to give easier intake. Somehow I doubt that slightly enriching the air being blown into the tank with CO2 is going to make much of a difference. The powerhead is internal =/ But I've ordered a special valve that will suck air and mix it in a chamber with the water from the outlet, and it will jet very fine bubbles into the aquarium...so I think I can do it with the co2 going into the valve directly. The valve is called an "Air Ventura" from Juwel www.juwelaquarium.de This idea conjures up visions of collapsed bottles and yeasty mixtures being sucked into the ventura. Better find one of those magnum champagne bottles for this project. Scott "kush" wrote in message ... Plans? We don't need no steenkin' plans! Poke a hole in the cap of a 2-liter soda bottle, insert some tubing and seal it with aquarium sealant. Wait a couple of days for it to set. Put 1.5 cups of sugar, 1/2 tsp. yeast and a pinch of baking soda (optional) in the bottle and fill to the shoulder with warm-not-hot water. Shake vigorously. Screw the cap on the bottle and insert the other end of the tube wherever you want the CO2 to go i.e., filter intake, powerhead, airstone, diffusing chamber. Wait an hour or so for the bubbles to start. Lasts approximately two weeks. If the bottle is going to be lower than the tank, for instance in a cabinet underneath, you probably want to put a one-way valve on the tubing. kush Phil Williamson wrote in message ... can you send me your plans and possibly a picture of your co2 injector? Regards, Phil.. "Jason @hotmail.com" jasonjudkinsspamremoval wrote in message . com... Hey folks, I built my DIY yeast co2 injector for my 63 gal tank, it works great! just used a 2 liter bottle, tubing, fine airstone w/ check valve... Each concoction produces co2 for about a week and a half... I am very happy with it So here is my question: Does anyone know of a good or common place to get a blow valve? (I.e. a valve that will discharge within a certain PSI range) I would like to make my DIY system fault tolerant, but I am just stumped on where to get the blow valve... any ideas? Thanks! -Jason -- Scott Lewis |
