Just set up a very simple DIY CO2 - a 3-liter bottle and a silicone tubing and a limewood airstone. Added 3 cups of sugar, 1 teaspoon of yeast, 2.3 liters dechlorinated warm water, and a handful of crushed coral. In 1-2 hours, hundreds fine bubbles per second come out of the limewood airstone, which place at the bottom of the tank below the AC HOB outlet.
