Product details
Ferrion (500ml) Liquid Iron Supplement is a concentrated liquid iron additive designed to supplement aquaria that contain iron-using, photosynthetic organisms. In marine reef and plant systems, iron can become a limiting factor for photosynthesis, so supplementing helps support groups such as zooxanthellate corals and their symbiotic algae, clams and their allies, macroalgae, coralline algae, and some mangroves/marsh grasses. Practically, Ferrion is dosed in measured amounts to target a low ppm iron range (commonly 0.05–0.10 ppm as a starting point) and is often used in systems with refugia or mud setups where plant growth is a focus.
Features:
- Highly-concentrated, stable iron solution intended for marine aquaria
- Helps supplement iron availability for photosynthetic/zooxanthellate organisms, coralline algae, and marine algae/plant growth
- Supports refugium and mud-system style setups where nutrient and mineral cycling matter
- Purified-water base with ultra-high purity materials (ingredients listed as purified water and sodium feredetate)
- Shake well before dosing to ensure even distribution
- Use aquarium testing to guide dosing and maintain iron within a target range, avoiding overuse
