Seachem Flourish Excel

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).

Directions

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

CAUTION: Do not eat drink or get into eyes. In case of eye exposure, promptly & thoroughly wash eyes with water & seek medical attention.

Good
Size: 3 Fl Oz (Pack of 1)
Whole family continues to purchase/use this sunscreen even though my child is no longer a baby. It does leave some white residue/cast. I haven't found a mineral sunscreen that doesn't.

No horrible white haze
Size: 3 Fl Oz (Pack of 1)
This is the first all zinc sunscreen I have used that has not turned my skin, a pasty white. However, it has dried my skin out so now I am mixing it with oil and rubbing it in. I know it's diluting the sunscreen in it, but at least it's natural and my skin is not dry.

The best!
This lotion will change your life. It smells SO good and leaves your skin incredibly soft. Super hydrating. It is great for after tanning. It will rehydrate your skin after that. I don’t know if it really locks in the color, or if that is just a high quality tan bed that I use. Either way- It’s a gem!
