5. (2 Pack) Seachem Flourish Excel, 2 L / 67.6 fl. oz.
Feature
(2 Pack) Seachem Flourish Excel, 2 L / 67.6 fl. oz.Organic carbon for the planted aquarium
Flourish Excel is a source of bioavailable organic carbon
250 milliliters treats 50 US gallons for 1 to 2 months
Description
Flourish Excel is a simple source of readily available organic carbon. All plants require a source of carbon. This is typically obtained from CO2, but, may also be obtained via relatively simple organic compounds (such as photosynthetic intermediates). Since both processes occur simultaneously one can derive a substantial benefit with the use of Flourish Excel either alone or in conjunction with CO2 injection. 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). Flourish Excel is an integral component of Seachem's plant products and is recommended for use with the entire Flourish line as well as our Flourite and Onyx gravels. Contains no phosphate or nitrate.6. Flourish Excel, 100 mL / 3.4 fl. oz.
