Seachem Flourish Tabs (40-pack)
$23.94
The premium root tab: a complete formula of over 15 nutrients including nitrogen phosphorus potassium, chelated iron and trace elements, tucked into the substrate for heavy root feeders like swords and crypts.
Pros
- A complete formula for the roots — macro and micro nutrients, over 15 in all
- Includes nitrogen phosphorus potassium, chelated iron and trace elements
- Just push a tab into the substrate near heavy root feeders — easy dosing, no cups to measure
- Balanced and gentle, shrimp safe, and it stays in the substrate with no algae bloom in the water
Cons
- A 40-tab pack costs more upfront than API tabs
- Feeds the roots only — pair with a liquid for water-column plants like stems and floaters

Alternatives
$28.99 · 90 / 100A
The best all-in-one for a low-tech planted tank: a complete formula with macro and micro nutrients dosed from a pump dispenser. One weekly dose covers nitrogen phosphorus potassium plus chelated iron and trace elements.
$17.85 · 82 / 100A−
Complete root tabs at a value price: slow-release nitrogen phosphorus potassium plus micros, shrimp safe. A cheaper, EI-style alternative to Seachem's tabs for heavy root feeders.
$10.52 · 92 / 100A+
The classic trace supplement — not a complete fertiliser. Flourish is micros and trace elements only, so it is best paired with a nitrogen phosphorus potassium source rather than run alone.
