C02 Red Sea Food Source: Sugar?
I have a beautiful, healthy, 37-gallon planted tank using "Red Sea Turbo CO2", with the food source and yeast.
I'm tired of spending $12.00/month (or $7.00 via mail order) for the refill kit. It seems to me this stuff is just sugar, with yeast added.
So, can I just use plain ol' table sugar instead? Can I take half of the yeast cannister and mix it up with plain table sugar as the food source? Better yet, can I just leave a little bit of the sludge from the previous month and add more sugar?
