It serves as an effective alternative or complement to CO2 injection, controls algae, and supports lush, vibrant planted tanks with easy weekly dosing. ## Description Product description Flourish Excel is a source of bioavailable organic carbon. All plants require a source of carbon. This is typically obtained from CO2, but, may also be derived from simple organic compounds (such as photosynthetic intermediates). Flourish Excel also has iron reducing properties which promote the ferrous state of iron (Fe+2), which is more easily utilized by plants than ferric iron (Fe+3). By dosing with Flourish Excel you bypass the involvement of CO2 and introduce the already finished, structurally similar compounds. It is in its structural similarity that Flourish Excel is able to be utilized in the carbon chain building process of photosynthesis. Simple chemical or enzymatic steps can easily convert it to any one to any one of the above named compounds (or a variety of others). Directions Add 5ml Flourish Excel to every 40 litres of water, once a week. For faster effect, increase the dose to 10 water. Shake well before use.
