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 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 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).
On initial use or after a major (> 40%) water change, use 1 capful (5 mL) for every 40 L (10 US gallons). Thereafter use 1 capful for every 200 L (50 US gallons) daily or every other day. For smaller dosing please note that each cap thread is approximately 1 mL.
DO NOT OVERDOSE
Because we love our plants so much and don't want to let them go, we only ship on Monday. Just kidding!
For the safety of these magical plants, we only ship Monday through Wednesday, and Friday. Orders placed after 1pm Pacific Time will be shipped the following day.
Rimless aquariums and other hard goods will be shipped Monday through Friday via UPS Ground or freight. When purchasing plants/livestock with any hard goods, they will sometimes be shipped separately; but don't worry, we'll be sure to keep you updated with your purchase!
Please make sure your shipping address is correct as we will not be held responsible for DOA due to an undeliverable addresses.
Hard goods can be returned up to 30 days after purchase for a full refund as long as the product is unused and new in box. We offer store credit for items that have been opened and used. Customer will have to pay for return shipping freight.
We are unable to accept returns for perishable items such as plants or livestock. However, feel free to reach out to us if you are unsatisfied in any way! We do provide 100% DOA (Dead On Arrival) protection.
If your plants arrived DOA (Dead On Arrival), please provide a clear picture of the plants sealed in its original packaging within 12 hours of the package arrival at the shipping address.
Send all pictures, along with your order number to firstname.lastname@example.org or through Facebook Messenger.
During winter (under 50°F at your location), please remember to add a heat pack to your order to receive our DOA guarantee. Orders without the purchase of a heat pack will not qualify for DOA replacements, refunds or credits.
Don’t worry, we’ll take care of your order as long as it fits within the guidelines above!
