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.

Meets the Specifications for VW TDI
Size: 1 Quart Pack of 6
I don’t get too excited about motor oil; it just needs to meet the specifications for the application. This oil meets the standards for VW TDI engines (VW 504.00 & 507.00) and several other European turbo diesel engines. While this type of oil is locally available, it is very costly if purchased locally by the quart. There are plenty of other brands like Liqui Moly and Mobile One that offer oils which will meet the specifications, so pick the one you like. After some research, I found there are no great deals in terms of cost, all of the oils that meet the VW 504.00 & 507.00 specifications are going to be on the expensive side. However, Castrol is the brand used by VW, so if that’s important to you, there’s your option. I have used this type of oil for several years and many thousands of miles with zero issues. If you do your own maintenance, you might as well save a little money and buy in bulk. Storage and shelf life of motor oil is not a concern.

Great oil for BMWs
Size: 1 Quart Pack of 6
Not much too say, it's the classic oil, only thing I can note is that it came with the old packaging and all that, but it works great for my car and runs smooth and without noises or temps, good value, and fairly fast shipping, good thing I can find it on here because none of my local auto stores had it on stock.
