Ferrum Lab 200ml

This 200 ml micronutrient product is intended for reef aquarium keepers who need to raise iron levels in seawater. Iron is a key element for coral photosynthesis, so supplementing it addresses a common gap in reef water chemistry, especially when test results show low Fe.

Why it matters

• Photosynthesis: iron plays an important role in photosynthesis, so supplementation supports the way corals feed.
• Coloration: the product is designed to support green coloration in corals.
• Predictable dosing: 1 ml raises iron by 0.001 mg/l (ppm) in 100 l of water, which makes the effect easy to calculate.
• Target range: the recommended iron level is 0.002–0.006 mg/l (ppm), giving a clear reference for adjusting the dose.

What it works with

The product belongs to the marine salt and reef supplement category and is intended for saltwater aquariums with corals. Dosing is based on the water volume in litres, so the amount per day scales with tank size. Because the manufacturer recommends testing water before supplementing, results should guide how much iron is needed.
