Seachem Flourish

Looking for a complete micronutrient fertiliser for your planted aquarium?

Seachem Flourish 250mL is a comprehensive plant supplement designed to provide essential trace elements, micronutrients, and beneficial compounds required for healthy aquatic plant growth.

Unlike macronutrient products (Nitrogen, Phosphorus, Potassium), Flourish focuses on the critical trace elements that are rapidly depleted in aquarium systems through plant uptake and water changes. Without these micronutrients, plants may grow slowly, appear pale, or struggle despite adequate lighting and CO₂.

What It Helps Fix

✔ Pale or washed-out leaves
✔ Weak new growth
✔ Slowed plant development
✔ Micronutrient deficiencies
✔ Poor colour despite proper macro dosing

How You Know You Need It

• You run a planted tank but don’t dose trace elements

• Plants grow but lack vibrancy

• You perform frequent water changes

• You dose macros but growth still feels incomplete

• You’re building a balanced fertiliser routine

If you're not dosing trace elements, your plants are likely missing key building blocks for optimal growth.

Dosage

Standard Dose: 5mL per 250L, once or twice weekly
For heavily planted tanks, dosage may be adjusted based on plant mass and demand.

Safe for freshwater planted aquariums and compatible with Seachem’s Nitrogen, Phosphorus, and Potassium supplements.

For balanced plant nutrition and consistent aquascape performance, Seachem Flourish 250mL is a foundational fertiliser in any serious planted tank routine.
