Seachem Flourish Excel 500ml

Seachem Flourish Excel is a bioavailable organic carbon source designed for planted aquariums. It provides aquatic plants with a readily available source of carbon and can be used either as an alternative to CO₂ injection or alongside a CO₂ system.

Flourish Excel is particularly useful for aquarists looking to support healthy plant growth without the equipment and complexity associated with CO₂ injection. It can also be used alongside CO₂ to provide additional carbon supplementation.

Important Information

Flourish Excel is not an algicide, although some aquarists have observed reductions in certain types of algae when using the product. It should not be overdosed or used as a direct spot treatment, as this can damage plants. Certain sensitive plants, including Vallisneria and Anacharis, may be more susceptible to higher doses.

When used according to the manufacturer's directions, Flourish Excel is considered safe for fish.
