Seachem Flourish Excel plant supplement 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 Excelâ„¢ plant supplement 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 Excelâ„¢ plant supplement either alone or in conjunction with CO2Â . The combination is particularly ideal for situations when continuing to add CO2Â could result in dangerously low pH levels. Flourish Excelâ„¢ 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 includes 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 Excelâ„¢ plant supplement does not contain these specific compounds per se, but one that is quite similar. By dosing with Flourish Excelâ„¢ plant supplement you bypass the involvement of CO2Â and introduce the already finished, structurally similar compounds. It is in its structural similarity that Flourish Excelâ„¢ 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).
Why use Seachem Flourish Excel?
Carbon is one of the most important nutrients required for healthy aquatic plant growth.
In high-tech planted aquariums this is often supplied through a CO2 injection system, but many aquarists prefer a simpler approach. Seachem Flourish Excel provides a readily available source of carbon that can be used in low-tech planted aquariums, alongside CO2 systems or in situations where installing pressurised CO2 equipment may not be practical.
Many hobbyists use Flourish Excel to support stronger plant growth, improve plant health and help create a more competitive environment against nuisance algae. It is particularly popular in planted community aquariums where aquarists want the benefits of additional carbon without the cost and complexity of a full CO2 system.
Frequently Asked Questions
Does Flourish Excel replace CO2?
Not exactly. This is liquid carbon, which is not the same as carbon dioxide. It does however still offer pretty notably benefits, especially in low tech planted tanks.
Is Flourish Excel safe for shrimp?
When dosed correctly, it is generally believed to be safe for freshwater shrimp and other invertebrates. As with all additives, avoid overdosing and monitor sensitive livestock closely.
Does it help with algae?
Although Seachem don’t market it for this purpose, liquid carbon is known to harm black beard algae.
Can I use it with CO2?
Absolutely. This can be used alongside CO2 and other fertilisers.
Can it be harmful to plants?
Vallisneria can be somewhat sensitive to liquid carbon, especially at higher doses.
