Can someone tell me PRACTICALLY how to make a DIY co2 system. Right now I
add 2 cups of sugar and a 1/4 cup of yeast to a 2 liter bottle which is
hooked up to the intake of my Eheim filter anf the bubbles last about 4-5
days!! Whats wrong?? Also, How many 2 liter bottles do I need for a
heavily planted 150 gln discus show tank??
