Brightwell Aquatics | Ferriorn

Ferrion by Brightwell Aquatics is a concentrated iron supplement formulated to support the health and growth of photosynthetic marine life—especially macroalgae! Iron is a vital micronutrient that drives photosynthesis, enhances nutrient uptake, and supports vibrant coloration and structure in species like Gracilaria, Caulerpa, Hypnea, and other commonly macroalgae.

This supplement is particularly useful in systems with refugiums or dedicated macroalgae displays, where iron levels can become depleted over time. Maintaining proper iron concentrations (around 0.05–0.10 ppm) helps prevent slowed growth, pale tissue, and nutrient imbalances that often appear in macroalgae tanks.

Ferrion’s high-strength, lab-grade formula requires minimal dosing, yet delivers consistent, long-lasting results without disrupting water chemistry. Designed for precision and purity, it’s an ideal solution for macroalgae-focused tanks aiming to maintain lush growth, healthy nutrient export, and overall system balance.
