Product description
A complex of micronutrients for healthy plant growth
Seachem Flourish is a multi-component fertiliser designed for aquatic plants in freshwater aquariums.
The product contains a rich blend of trace elements, such as iron, boron, zinc, manganese, copper, molybdenum, cobalt, chlorine, sulphur and sodium, which play a vital role in plant metabolic processes.
An adequate supply of trace elements influences the proper functioning of photosynthesis, the intensity of colouration and the overall health of plants.
Supplementation of selected macronutrients
The formula has been enriched with selected macronutrients, including calcium (Ca), magnesium (Mg) and potassium (K₂O), which support the stable growth and development of the root system and plant tissues.
The content of nitrogen (N) and phosphorus (P₂O₅) is kept at trace levels, meaning it does not interfere with the established fertilisation strategy and does not need to be taken into account when calculating macronutrient rates.
Reliable support in community aquariums
This product has been designed as a safe, all-purpose plant supplement for aquariums. Regular use helps prevent micronutrient deficiencies, which often occur in tanks with moderate lighting and without an intensive fertilisation regime.
Flourish provides a solid foundation for trace element supplementation, improving plant health without the risk of overloading the system with macronutrients.
Purpose
Seachem Flourish is designed for use in freshwater aquariums, particularly in community tanks where plants complement the fish population.
The product works well as a basic micronutrient supplement in aquariums with moderate plant growth rates.
Due to its trace levels of nitrogen and phosphorus, the product should not be treated as a source of macronutrients in fertilisation management – instead, it provides a safe and stable supplement of trace elements.

Tip1:
To provide plants with a full spectrum of nutrients, Flourish should be used in combination with fertilisers from the Macro group, in particularnitrogen (N) and phosphorus (P). This combination guarantees that plants have access to all the necessary elements for healthy growth and intensive development.
Tip 2:
How do you use Flourishcorrectly?
The standard dosage is 1 capful (5 ml) per 250 litres of water, to be used once or twice a week.
Once openedit is recommended that you store the packaging in the fridge, although this is not essential.
Depending on the growth rate and requirements of the plants, the dosage can be increased or decreased accordingly, adjusting it to the individual needs of the aquarium.
Before each use, it is advisable to shake the bottle well to distribute the active ingredients evenly and ensure their full effectiveness.
