Liquid nutrient for lush and healthy aquarium plants
Excellent source of bio-available, organic carbon for plants
Easy-to-use and convenient alternative to CO2 injection
Flourish Excel is a simple source of carbon for aiding growth of aquatic plants. Designed to make plant-keeping easier without carbon dioxide injection. Use it alone, or if you choose, with carbon dioxide injection. Keeps iron in a reduced state that's easily utilized by plants. 1 ml treats 10 gallons. Recommended for use on a daily to every other day basis.

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). The use of either CO2 injection or Flourish Excel does not necessarily negate the use of the other. Because the processes of producing photosynthetic intermediates and building onto them occur simultaneously, one can derive a substantial benefit with the use of Flourish Excel either alone or in conjunction with CO2 . The combination is particularly ideal for situations when continuing to add CO2 could result in dangerously low pH levels. 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).
The reason plants need CO2 is to produce longer chain carbon compounds also known as photosynthetic intermediates. Photosynthetic intermediates include compounds such as ribulose 1,5-bisphosphate, and 2-carboxy-3-keto-D-arabinitol 1,5 bisphosphate. Although the names are complicated, the structures are quite simple (5 carbon chains). Flourish Excel does not contain these specific compounds per se, but one that is quite similar. 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).
Seachem's philosophy is that the knowledgeable hobbyist makes the best customer. This is reflected in solid and reliable customer education and support as well as products proven in science and performance. While Seachem has grown rapidly into a national and international firm, it retains the culture of a small company and is readily available to its customers.
For over three decades, Seachem has been a company rooted in sound science. Their experience in the hobby and an educated staff of chemists and biologists are part of the package when you purchase Seachem products. Seachem remains as one of the few surviving independent and privately owned pet care companies. Seachem is owned and operated by hobbyists. All of their employees are hobbyists who maintain aquariums at home and at the office. Seachem itself was started because one such hobbyist found the available solutions to aquarists' problems wanting. This resulted in Seachem's very first product: Cupraplex™ (today known as Cupramine™). Over thirty years later Seachem is still approaching old problems in a new way.
Is Flourish Excel a replacement for CO2 in a planted aquarium?
Yes and no. It provides the same benefit as CO2, i.e. it provides the plants with a source of carbon for growth just as CO2 provides them with carbon. However CO2 by itself will give you quantitatively more growth than Excel by itself, although Excel does provide a substantial amount in comparison. If CO2 is a 10, Excel is a 6-7. Using both together provides additional benefit. One of the advantages of the Excel is no up front equipment costs and complexity of valves, hoses and regulators, etc.
Is it better to add Flourish Excel at night or in the morning based upon plant carbon uptake physiology?
Carbon intake is a function of photosynthesis. Based on this, it would be ideal to dose Flourish Excel during the day. But given that Flourish Excel can stay complexed as a carbon source for up to 24 hours before it dissipates, you can dose at any time of the day and the product will be available for the next 24 hours. Flourish Excel is not carbon dioxide and there is no impact on pH using Flourish Excel.
Will an airstone or surface agitation decrease the effectiveness of Excel as it would decrease the effectiveness of CO2 injection? What effect would it have on Excel?
An airstone or other surface agitation will not impact the effectiveness of Flourish Excel. Flourish Excel is not CO2, it is simply a readily available source of carbon. This is an intermediate source and more readily available than CO2 and will not interfere with the uptake of CO2 as a carbon source.
I've been using Flourish Excel for four days, and I've noticed that my Anacharis seems to be dying, while my other plants are doing fine. Why is this?
Anacharis is a particularly sensitive species (known to be sensitive to high temperature, trace copper, formaldehyde etc.). It is also sensitive to Flourish Excel. If you have Anacharis in an aquarium in which you are dosing Flourish Excel we recommend using Flourish Excel every other day rather than daily.
Re-create a unique and natural aquatic ecosystem indoors by adding a planted aquarium to your home. Planted, aquariums contain live underwater plants (and fish, if you'd like), which closely replicate the beautiful, relaxing environment.
Anyone who has seen a photograph of a lush, verdant setup with a school of jewel-like tetras knows the beauty of a freshwater planted aquarium. Many hobbyists avoid adding live plants, believing they are too fragile or too difficult to keep.
