I am useing yeast sugar co2 in my 50 gal tank i have 2 1.89L bottles i fille one up on fri, and the other the following friday and rotate. the only thing is i am really only getting 7-8 days max out of 1 bottle and it is completly dead. i mix in 3/4 cup of sugar in warm water then add 2 cups coll watter then mix (disolve completly)1 full teaspoon of yeast into the last 2 cups of water and add it in and shake it up reall good. Now by all means i am very impresed about how god it works after the first 12-18 hrs i satrt getting a buble every 3/4-1 sec until about the 4-5 day mark the it gose to 1 every sec-1.5sec for the next few days and then it is complety dead after 7-8 days, is that normal for that mixture or can i mix it diferent to get the same amount but it last longer? i just set one up for my 10g tank exact same but only 1/2teaspoon yeast the bubles are 7-12 sec apart this sould lasts longer right.

you're running out of sugar. a 2 liter bottle should have about 2 cups of sugar.

i use the following successfully: put two cups of sugar in the bottom of your bottle and add hot tap water. shake well to dissolve and let sit for about 15 minutes. add 1/2 tsp yeast and a pinch of baking soday. bubbles in 15 minutes or less.

if you make bread without a bread machine, you often start yeast with some sugar in 105F water.
