Seachem Flourish Excel Plant Carbon Co2 Alternative 250/500ml

Seachem 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. Seachem 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).

Good quality but I sure don't taste spicy and pricey
These are big good quality smoked oysters. The smoke flavor was too strong for me and they were not one bit spicy even with a pepper in the can which wasn't even mild eaten by itself. They are also pricey compared to other brands which I like better after the comparison. If you like spicy get another brand that costs less like chicken of the sea and add your favorite hot sauce like sriracha or tabasco etc to get your spice flavor and heat level

Love them, eat this brand all the time
These are the best! Just a dash of spice and in pure olive oil! I have bought them repeatedly! Oysters are so good for us women! They support bone health (Vitamin D, Zinc, Copper), iron for energy, and B vitamins for brain function, with studies even suggesting oyster peptides may protect ovaries; they also provide Omega-3s for heart/skin health and Selenium for thyroid function, all while being low-calorie. I turn my friends on to them who have never tried smoked oysters with a dab of Nancy's probiotic cream cheese on crackers or my favorite, Celery!
