Seachem Flourish 4 Litres

• Comprehensive supplement for the planted aquarium.
• Provides micro elements, trace elements and other nutrients.
• Does not contain significant levels of nitrogen or phosphorus.

Flourish is a comprehensive plant supplement for the natural freshwater aquarium. It contains a rich assortment of important micro elements, trace elements and other nutrients. These include calcium, magnesium, iron and other important elements that have been shown to be beneficial to aquatic plants. For macro element (NPK) fertilization, use Flourish Nitrogen, Flourish Phosphorus or Flourish Potassium as needed. Flourish is safe for invertebrates such as shrimp.

Flourish is designed to be used in conjunction with other macro and micro-nutrient supplements. Other manufacturers try to include ALL necessary nutrients, leading to overdoses of micro-nutrients in an attempt to raise macro-nutrient levels.

Compatibility

What it is. Flourish is Seachem’s comprehensive trace-element supplement for the planted freshwater aquarium — a broad spread of micro-nutrients (iron, manganese, boron, zinc, cobalt, copper, molybdenum) plus calcium, magnesium and potassium, but deliberately light on nitrogen and phosphorus.

Where this sits in the Seachem range. Flourish is the base trace-element layer, not a complete fertiliser. Seachem’s own guidance is to pair it with nutrient-specific supplements — Flourish Nitrogen, Flourish Phosphorus, Flourish Potassium — where the tank needs those macro-nutrients too.

Best suited to. Any planted freshwater tank, and safe alongside invertebrates including shrimp. Used as directed it does not alter pH.

Dosage & Directions

Seachem’s own dose. Use 1 capful (5 mL) per 250 L (60 US gallons), once or twice a week. Each thread on the cap measures roughly 1 mL, for dosing smaller tanks.

After opening. Seachem recommends refrigerating the bottle three months after opening.

Handle it as a chemical product. Aquarium use only, and keep away from children — Flourish contains 1,5-pentanedial (glutaraldehyde) and may produce an allergic reaction in some users.

Freshness & Storage

Every batch we dispatch carries a minimum of 6 months’ remaining shelf life. Store this product in a cool, dry place away from direct sunlight, with the cap or inner foil closed tightly after each use.
