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 Graphic Novel
Format: Paperback
A good graphic novel full of action and well-done graphics. The story is fast paced and will keep your interest. The plot is well told and holds the premise for further stories in a series. A good read.

Extremely fun!
Format: Paperback
I couldn't stop laughing while reading this. It's very well written, well drawn, and the overall quality (both physical & story wise) is very good. Just finished reading this volume, and I have nothing but good things to say about it. Ogami (the main protagonist) is a very fun character to follow through his dilemmas. Definitely looking forward to reading Volume 2!

pretty funny for a 39 year old, but...
Format: Kindle
I loved the premise of a "middle aged" hitman turning into a middle school boy, but there are some iffy bits for teens. When a divorced, middle aged hitman is turned into a middle school boy, shenanigans happen. I'm not sure if Kill Blue is a dark crime or school life comedy manga; I think it's a bit of both. The author does a great job portraying how adults see the current generation, obsessed with social media, etc. I loved how our grouchy, introverted ML starts to love learning, and begrudgingly becomes more social. He has a typical goofy sidekick and other side characters. The FL is a beautiful (?) middle school girl who keeps being hassled by teen boys and enemies of her father, and the ML reluctantly steps in to help. If you like this kind of manga, I'd recommend Sakamito Days, where the ML is already happily married. ********Spoiler Alert********* The whole idea that " I'll have to marry a middle school girl", when I'm really a 39 year old man is creepy. Even if the 39 yr old is in a middle school body. If this manga turns into a long series, and his character marries the girl, it will still be creepy. That's my parental concern.

Fun series starter
Format: Kindle
This was fun. Juzo Ogami is 39, legendary assassin and a divorced father of one. A bee sting transforms his body back to a 13-year-old’s, so his boss sends him to scout a middle school for his daughter—as a student there. It’s not easy for Ogami, who is a school drop-out and doesn’t know how to talk to children. On a first day, he’s pegged to be the class loser. But to his surprise, he discovers he loves learning. If only he could study in peace, but all sorts of pervs and kidnappers disturb the students and he has no choice but to step in. Anonymously. The real trouble begins when the scientist trying to find a solution to his age problem—his ex-wife—learns that to infiltrate the pharmaseutical company responsible for the age drug, Ogami needs to marry the owner’s daughter, who just happens to be his classmate. No way is he going to date a girl the same age as his daughter, not even to save her from worse suitors. Right? This was a fun start to a series. Ogami was slightly different age-change protagonist with his world-weariness and clear understanding of what is appropriate for someone his age. He changes a lot during the first volume already. It will be fun to see where that’ll lead. Art was good.
