qBenefitsr CO2 LIQUID B2 promotes photosynthesis of waterweed by increasing the inorganic carbon (e.g., carbon dioxide, carbonate ion) of the water, without forced administration of CO2 gas. All of the plants including the waterweed obtain energy through photosynthesis, promoting photosynthesis can promote plantsf growth. A higher growth promotion can be expected when CO2 LIQUID B2 is used together with FLORA CELL and FERRO CELL. qMechanism of increase of carbon dioxide concentrationr Generally forced administration of CO2 gas into the water is used to increase carbon dioxide concentration. CO2 LIQUID B2 itself contains no carbon dioxide, it uses calcium carbonate (CaCO3) contained in the water as carbon source of CO2. CO2 LIQUID B2 supplies carbonate ion to the water by binding calcium carbonatefs calcium with a special ingredient formulated. Part of this carbonate ion (CO32|) becomes bicarbonate ion, and pH becomes increased due to the increase of calcium ion in the water. While as a mild acidity is kept by a formulated pH buffer, bicarbonate ion becomes carbon dioxide, and thus increases the carbon dioxide concentration. qUsager Use in the proportion of 40-50ml of CO2 LIQUID B2 to 100L of water. Use once in every 14 days to keep the effect.
