Extra iron for red and fast-growing aquarium plants — UV-stable and long-lasting efficacy
Sera Flore 2 Ferro — specially chelated iron for densely planted aquariums
✅ Level: Easy — Simply dose. No special knowledge required.
Red and fast-growing aquatic plants have a high iron requirement — a deficiency quickly leads to faded leaves and reduced color development. Sera Flore 2 Ferro has been specially developed for densely planted and brightly lit aquariums. Thanks to specially chelated iron, the iron remains available for several days — even in aquariums with a UV-C water clarifier that quickly breaks down normal iron complexes. Nitrate and phosphate-free, safe for all invertebrates.

❓ Frequently Asked Questions
What is the difference with Sera Florena?
Sera Florena is the basic plant fertilizer with iron and trace elements. Sera Flore 2 Ferro provides extra iron specifically for red and fast-growing plants with a high iron requirement — ideal as a supplement to Florena.
Why is UV stability important?
UV-C devices quickly break down normal iron complexes, making the iron no longer available to plants. The chelated iron in Flore 2 Ferro remains stable for several days — even when using UV-C.
Is Flore 2 Ferro safe for shrimp?
Yes — Sera Flore 2 Ferro is nitrate and phosphate-free and safe for all invertebrates, including shrimp and snails.
