Seachem Flourish Excel Organic Carbon 17 oz Pack of 4

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).

• Provides aquarium plants with a source of essential carbon
• Great for use alone or in conjunction with CO₂ injection
• Iron reducing properties to promote ferrous state of iron

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).

Seachem Flourish Excel is an integral component of Seachems plant products and is recommended for use with the entire Flourish line as well as our Flourite and Onyx Sand substrates. Contains no phosphate or nitrate.

Directions: 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.
