Seachem® Flourish Excel™ Organic Carbon Source for the Planted Aquarium 250 MlFlourish 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.

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

Fantastic Dog Toy!!!
Color: Purple
This is a great toy!!! My dog has lots of toys. But one of the problems is he has trouble getting the squeaker to squeak. He's an 18 lb terrier mix, and those squeakers are just elusive. Breaks my heart. This one, though, the squeakers (there are two) are in small areas (head and tail), that are easy for him to get his whole mouth around and squeak. They also don't move, which also makes them easy to squeak. So he's been squeaking up a storm since he got this! Other plusses: * The material is great (soft, furry material, that seems to be of good quality). * The toy expands and contracts, which is fun. * It's pleasant to look at. All in all, I'd say this is one of the best dog toys I've ever bought for my dog. Highly recommended!

Great Toy in Spite of Everything.
Color: Purple
My dog is a border collie. She loves chewing, fetching, tug of war and catch. The first day we had this toy she chewed off two of the feet. I didn't give it much of a life span. Two weeks later she chewed off a third foot. Miraculously no stuffing was exposed. It has now been a month and the toy is still going strong, albeit with one foot! She loves it. It is now June 1st. It has been almost three months and I am retiring the toy. It no longer has any feet and the tail has been ripped open and stuffing is coming out. All in all I think I got my money's worth from this toy. I ordered another one. She still loves it!

Awesome, but not the best squeakers.
Color: Purple
I bought the orange gecko for my 5-month-old Corgi puppy. He absolutely loves it. He came up with a "game" (sort of) where if I pick it up and start squeaking one of the ends/squeakers really quickly over and over, he'll grab the other end/squeaker and start doing the same thing with me. It was really cute until one of the squeakers stopped working about a week after I bought it... but I guess the toy wasn't too expensive, and he doesn't really seem to mind that one of the squeakers doesn't work anymore. I might buy another next time I do an Amazon order (so I can get the free shipping) and see if it lasts a little longer.
