Flourish Trace 250ml

Flourish Trace is a liquid micronutrient fertilizer for planted freshwater aquariums. It supplies boron, zinc, cobalt, manganese, copper, molybdenum, nickel, rubidium and vanadium in measured amounts, so keepers who already dose macronutrients can cover the trace element side of the plant diet separately.

Why it matters

• Separate formula: trace elements are packaged apart from the main nutrients, which the manufacturer says prevents slower-used elements from building up while faster-used ones run out.
• Guaranteed analysis: the label lists minimum concentrations for each element, including both total and soluble zinc, manganese and copper.
• Simple dosing: one 5 ml cap per 80 litres of tank volume, applied twice a week, gives a fixed routine that scales with tank size.
• Flexible use: it can be used alone or alongside the Flourish preparation.

What it works with

The product is intended for planted tanks where trace elements are dosed as a separate step from macronutrients. The dose scales with volume, so the same bottle serves small and large aquariums; for example, a 240-litre tank receives 3 caps per application. It is designed for use in combination with the Flourish preparation or as a standalone trace supplement.
