Seachem Flourish®

Flourish is the comprehensive micronutrient and trace element supplement most planted tanks start with.

Key features

• Supplies the broad range of micronutrients and trace elements aquatic plants draw on, including iron, calcium and magnesium
• Deliberately low in nitrogen and phosphorus, so you are not forced to add macros you do not need
• A sensible first fertiliser for a low tech planted tank with modest lighting
• Pairs with Flourish Nitrogen, Phosphorus and Potassium when you want to raise one element on its own

That split is the point of the range. A stocked tank often has plenty of nitrate and phosphate from fish waste already, and a single all in one bottle would push those higher just to deliver traces. Flourish handles the trace side and leaves the macros to you.
