Excel is the shorted name for a very popular commercial product called Flourish Excel made by Seachem.

This product is a bottle of liquid which provides a ready available source of organic Carbon for aquatic plants and can be used as a CO2 substitute. This causes extra plant growth and less algae.

Side effects[edit | edit source]

Algaecide[edit | edit source]

It's been noticed that even at recommended doses Excel kills of algae, and is popularly used to kill some species of Algae like Hair Algae at 2-3x the recommended dosage. However this is not with the manufacturer's recommendation.

Nitrogen[edit | edit source]

Some Excel users have noticed a rise in nitrites or nitrates after introduction. Seachem's position is Excel shouldn't affect the nitrogen cycle of an aquarium, but there are online reports of this happening. (Possibly due to the product killing off algae).

Invertebrates[edit | edit source]

Excel is reportedly hard on Invertebrates.
