Seachem Flourish Excel 100ml

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. 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).

Another useful side benefit (which Seachem is not allowed to put on the label due to EPA guidelines in the USA) is that it interferes with the metabolic abilities of algae.

Used at a regular doses it will prevent many types of algae and at a higher dose rate (double) it will kill various algae. The most susceptible are the black, hair, and beard forms.

Dosing instructions.
