The Enhancer is an all natural CO2 generator made from 100% organic ingredients. This safe and effective solution for CO2 supplementation creates a blast of CO2. Activate The Enhancer by adding 1 litre of warm water, placing the lid back on, removing the sticker on the lid, covering the small hole with your thumb and giving the bottle a quick shake. The Enhancer works off the natural phenomena known as photosynthesis and will begin to disperse CO2 within a few minutes of being activated. For optimal performance shake The Enhancer every third day in your Grobo. The simplicity and ease of use, along with the fact that The Enhancer does not produce heat or require any additional equipment, makes this the future of CO2 production.
