El CO2 in the aquariumIt is very important, not only for our animals, but also for the plants that we have in the pond. It is for this reason that today we want to show you a new way to produce CO2, in a very efficient and long-lasting way. To make this homemade CO2 for aquariums you will need the following: 1 bottle of one and a half liters of soda, 1 serum dispenser that brings the bubble counter and the non-return valve, a cup of sugar, an envelope of bicarbonate, a tablespoon of yeast tea and a cup and a half of hot water.
The first thing you should do is prepare the dropper, for the system, making a small hole in the lid and inserting the dropper, then you should seal it with a little silicone on both sides, to avoid any type of leak. In a bowl you should put a cup and a half of hot water and a cup of sugar, trying to dissolve the latter in the best possible way. A jelly will form that you must mix with the bicarbonate.
Once a uniform mixing, put it in the bottle and put it in the refrigerator for several hours, until it has solidified enough. I recommend that you put it in the refrigerator on its side so that the jelly is on a slope and covers most of the bottle.
When the jelly is ready, the next day, fill the bottle with warm water, leaving approximately 7 centimeters empty, so that there can be room for fermentation. Immediately afterwards, add a tablespoon of yeast to the bottle, avoiding stirring or shaking. Add a little water to the dropper of the serum and once it is ready, put the cap on the bottle, trying to tighten it as well as possible and connecting the hose at the end of the serum dispenser to the aquarium internal filter.
