Seachem Flourish Excel

Description

Seachem Flourish Excel is a top-tier liquid
CO
2
supplement and algaecide that is an ideal alternative to setting up a
CO
2
system, which is often impractical in smaller planted tanks.
The most popular alternative to
CO
2
injection for high growth tanks.
Uses:
Flourish Excel™ acts as an alternative to
CO
2
injection in "low tech" tanks.  Used at standard dosage, it can often double the growth rate of plants and provide for much denser and healthier plant growth.  If you keep any plants that are somewhat demanding or are just interested in increased the growth rate of your planted tank,
Flourish Excel™ is an excellent choice.  We use this at Aquatic Arts in all of our commercial aquatic plant systems as pressurized
CO
2
is not practical for us (as it is not practical for most people).
From the manufacturer:
Flourish Excel™ is a source of bioavailable organic carbon. All plants require a source of carbon.  This is typically obtained from CO
2
, but, may also be derived from simple organic compounds (such as photosynthetic intermediates).
The use of either CO
2
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 CO
2
.
The combination is particularly ideal for situations when continuing to add CO
2
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
).
Directions from the manufacturer:
On initial use or after a major (> 40%) water change, use 1 capful (5 mL) for every 40 L (10 gallons*).  Thereafter use 1 capful for every 200 L (50 gallons*) daily or every other day.  Dosing may be slowly increased in high-growth aquariums.  For smaller dosing please note that each cap thread is approximately 1 mL.
