Seachem Flourish Trace 250mL
If your aquarium plants look pale, washed out, or are growing slowly despite dosing a comprehensive fertiliser, they may be lacking trace elements.
Seachem Flourish Trace 250mL replenishes essential trace elements that are rapidly depleted in planted aquariums. Unlike macronutrients (nitrogen, phosphate, potassium), trace elements are required in smaller amounts but are just as critical for proper plant metabolism and colour development.
Over time, regular water changes and plant uptake strip these micronutrients from the water column — and without replacement, growth stalls.
What It Helps Fix
- Pale or dull leaf colour
- Slowed growth despite good lighting
- Poor overall plant vitality
- Weak new shoots

My aquarium plants were turning pale after several months of using only a macronutrient mix. After adding Flourish Trace every two weeks, the leaves became vibrant and new growth appeared quickly. It’s a simple solution that makes a noticeable difference.

I’ve had a planted tank for over a year and noticed my stem plants were weak and yellowing. After switching to Flourish Trace, the colour improved and the new shoots grew stronger. Works well with my existing lighting setup.

This product fixed a long-standing issue with dull plant colour. I used it once a month and saw visible improvement in leaf intensity within a few weeks. Easy to dose and no side effects.
