Review on 🌿 Enhanced DIY CO2 Generator System Kit: Pressure Gauge, Air Flow Valve and CO2 Diffuser for Optimal Water Plant Growth in Aquariums by April Goracke

1 level for plants growth. Can easily last a month. 1 cup of water is 235ml, so 3/4 cup is about 200ml. If you have a scale I suggest using it for the dry weight of citric acid and baking soda. I double ml and gram so the chemical reaction takes longer. You just have to change every 28 days. We leave it at the 2-3 bp level. I don't turn it off at night, but I have an air pump that shuts off so I don't gas the fish. If I leave it on, when my light comes on, the air turns off and the light comes on (beam 2) and then the plants have free access to CO2 for immediate absorption during the start of their 13 hour photosynthetic period. that I make available to you. I can get 4 to 8 inches of growth per day on most of my plants. I suggest you buy a 5lb bag of citric acid and a 13.5lb bag of baking soda from Amazon because it's so much cheaper than in store. Yeast requires too much fuss. The chemical reaction is much stronger in controls. The needle valve works. The pressure gauge works. All you have to do is start the process by sliding Bottle A into Bottle B. Do this until the bottles feel hard and the pressure gauge reads between 1kg and 2kg. Then turn on the tap and bam! C02 in your aquarium to keep your plants happy and healthy. Apologies for the book but I found it most useful for the c02 self-made man.
