Seachem Reef Iron

Seachem Reef Iron is an iron supplement for reef aquariums that supports the growth and coloration of corals and macroalgae by enhancing iron levels, which assists in nitrogen uptake.

  • Iron Supplement for the Reef Aquarium
  • Concentrated 5,000 mg/L Iron
  • Supports Growth and Coloration
  • Assists in Nitrogen Uptake

Iron is an essential element required in metabolic processes, protein synthesis, and growth of corals and macroalgae. Iron supplementation can enhance coral and macroalgae growth and color – particularly yellow and green colors in corals. In systems supported with nitrogen and phosphorous supplementation, iron utilization rates may be increased as iron assists in assimilation of nitrogen.  

Iron supplementation can enhance coral and macroalgae growth and color – particularly yellow and green colors in corals.

Supplementing with Reef Iron™ provides a safe means of increasing iron concentrations. Reef Iron™ is ideally suited for use with an aquavitro® sentia™ dose doser to maintain iron at a consistent concentration based on your aquarium's unique demand but is easily dosed manually as well. Ideal iron levels will vary but natural seawater generally ranges from 0.003–0.01 mg/L iron. Reef aquariums are often kept at higher levels for optimal coloration and growth. For optimal macro algae growth, many find 0.05–0.1 mg/L to be beneficial. Use Reef Nitrogen™, Reef Phosphorus™ and Reef Potassium™ to maintain optimal nitrogen, phosphorus and potassium levels.

Directions:

Beginner
Use ½ cap (2.5 ml) per 160 liters (40 US gallons) twice a week or as needed to maintain desired iron levels.

Advanced
The beginner dose raises iron by 0.08 mg/L. To target a specific iron level, increase dose according to the following formula: 0.195vn=m where v= volume of tank in liters, n=desired iron increase, and m= volume of product to use in ml. For example, to raise 160 liters by 0.08 mg/L iron you would use 0.195*160*0.08 resulting in 2.5 ml to dose. For reference: 1 US gallon=3.8 L.

Works quickly to calm itch
Size: 6.76 Ounce (Pack of 1)
I had an itchy outbreak on the back of my hand the day this product arrived. Perfect timing. Applied Avene and within a short time the itch calmed almost 100%. Slept through the night and this morning, the red rash is about 95% healed. So glad I bought this. Just another old age issue to deal with.

Loved this cleanser
I really love this cleanser. I use it every night to take off my sunscreen and my skin looks great. I enjoy that it doesn’t dry out the skin and it’s great for mascara. It’s very gentle as well and doesn’t sting your eyes. Will be buying again once I’m done.

Product review from a teenage girl
Has helped my fungal acne very well and has calmed down my breakouts I get monthly. There’s no scent and it feels very soft in the skin. Easy to rinse off and easy to use. Helps out my dry skin and makes me feel smooth after using.

Gentle and non-greasy cleanser.
Gentle on mature skin. No fragrance. Non-greasy. This is my double cleanser to remove makeup and this first step gets my face make up free and feels very clean.

Game changer
I use this cleanser with the other cleanser they have, the green one. It’s actually crazy how much it changed my skin routine. I didn’t change my products and only my cleansers and there was a huge improvement. Using them both together feels very nice, there is literally a slight glow on my face after i’m done washing it. The cleanser itself is an oil and helps get my makeup off well. My face is usually oily but my t-zone can be a bit dry, these combined helped my face go back to a “normal” balance. So happy with my purchase, definitely recommend.
