Pet Forum / Aquaria / Plants / December 2003DIY CO2?
I have a 13 gallon with 15 W of lighting and light to medium planting. I am hoping to increase this to medium to heavy. I have heard that using CO2 will help the plants. I was thinking somethng along the lines of yeast/sugar in lemonade bottles method. Yeast/sugar/water bottle ===(CO2)=== primary backwash/emergency spill bottle ===(CO2)=== secondary backwash/emergency spill bottle ===(CO2)=== Aquarium. Anyone got a recipe, such as ratios of yeast : sugar : water? Or other ideas and suggestions? Comments appreciated, Marcus on www.aquarticles.com in the plants section there are several articles on methods and quantities of sugar and yeast for a co2 reactor. i personally use 1/2 cup sugar, 1/2 tsp. yeast and enough water to fill the bottle 2/3 of the way up in a 2 litre soda bottle. in the cap of the soda bottle, i drilled a hole, inserted airline tubing, siliconed it to seal, put an airstone on the other end and put it in the aquarium. it is bubbling within a couple hours. i usually replace it or add more sugar every 1-2 weeks. > I have a 13 gallon with 15 W of lighting and light to medium planting.

Only problem with DIY CO2 is that is is nearly impossible to regulate. But it works well. I personally used the 64 oz plastic juice containers that have the screw on lid. Take the lid off and drill a hole in the top that is rougly 1/2 to 2/3 the diameter of the airline tubing. Cut a severe angle on the airline tubing so it is pointy and push/pull the pointy end through the cap until it's in about an inch. The airline, at the point where it goes through the cap should be pinched pretty good, but you should be able to blow air through the tubing. Then mix up your sugar with very warm water until the jug is about 2 inches from the top. Add the yeast and shake again. I let it rest a day before hooking it up to the aquarium. When I would change out the jugs, I'd have one ready to go from the night before, then uscrew the cap and remove the old jug, and then replace it with the new batch. Just keep a couple of juice jugs lying around. I used a cup of sugar, Warm water and about 3/8 of a teaspoon of yeast. The brew would last about 10-14 days.

When I was using CO2 (my plants are doing very well without it now) I used a pair of two-liter pop bottles hooked together with a T-connector, with a check valve between the bottles and the tank. I think two backwash bottles may be overkill, but on the other hand it won't hurt anything. My check valve saved me once or twice, so *some* form of protection is a good idea. I used two bottles so that I could change one each week, keeping (in theory) a more consistent CO2 flow going. The recipe I used was 1/2 bottle of warm water, 1.5 cups of sugar, and one teaspoon of Red Star yeast. I used the Flieschmanns (blew the spelling on that one!), but I found that Red Star worked a lot better. -- www.ericschreiber.com > >Yeast/sugar/water bottle ===(CO2)=== primary backwash/emergency spill bottle > >===(CO2)=== secondary backwash/emergency spill bottle ===(CO2)=== Aquarium.

I use two plastic bottles and change one every week for a more consistant system. My recipe is 2 cups sugar, 1/2 pack regular yeast, warm water, stir in a jug then pour into bottle. Top up with more water to fill bottle 2/3. The hoses come up up from the bottles and into the bottom of a film canister (drill smaller holes) then drill another hole in the cap of the canister and insert one end of airline tubing. The other end goes into the water. Works AMAZING! |
