Unlock the full potential of your planted aquarium with Seachem Flourish Iron™. This highly bioavailable iron supplement is specifically formulated to prevent and correct iron deficiencies, which are a primary cause of poor growth and pale, chlorotic leaves. Give your plants the essential micronutrient they need to achieve deep, rich green coloration and thrive.

Key Features & Benefits:

  • Prevents Chlorosis: Directly targets iron deficiency, the main cause of yellowing leaves, especially in new growth.

  • Highly Bioavailable: Features a ferrous iron gluconate compound that plants can absorb and utilize immediately and efficiently.

  • Promotes Vibrant Coloration: Ensures your plants can produce lush, green chlorophyll for stunning visual health.

  • Ideal for Fast-Growing & Demanding Plants: A must-have for keeping advanced species like red plants, carpeting plants, and stem plants healthy and vibrant.

  • Safe for All Aquaria: Perfectly safe for fish, invertebrates, and beneficial bacteria when used as directed.

Product Details:

  • Product Name: Seachem Flourish Iron™

  • Size: 100 ml

  • Type: Comprehensive, highly bioavailable iron supplement.

  • Use: For all freshwater planted aquariums.

How To Use:

  • Dosage: Use 1 capful (5 mL) for every 200 L (50 US gallons) daily or as needed.

  • Application: For precision dosing, use a syringe. Disperse evenly into the aquarium. For maximum benefit, add after a water change.

  • Note: Dosage can be adjusted based on plant density and individual tank needs. Iron is typically consumed rapidly, so more frequent, smaller doses are more effective than one large weekly dose.

FAQ Section (Suggested for the product page):

Q: How do I know if my plants need iron?
A: The most common sign is chlorosis—yellowing or pale leaves, especially in the newest, youngest growth while the veins may remain green. Stunted growth is another key indicator.

Q: Can I overdose with Flourish Iron?
A: While safe when used as directed, extremely high doses of iron can be detrimental to some plants and shrimp. It is always best to start with the recommended dose and adjust gradually based on plant response.

Q: Is this enough on its own, or do I need other fertilizers?
A: Flourish Iron™ is a supplemental source of one specific micronutrient. Plants also require macronutrients (Nitrogen, Phosphorus, Potassium) and other micronutrients. For a full fertilizing regimen, you will need a comprehensive fertilizer like Flourish® or the full Flourish® range.

Nice Fit
Color: Black, White, Light Gray, Size: 3X-Large
I picked this up looking for something simple but clean, and it delivered. The fit is comfortable, the material feels solid, and it looks good without needing much effort. It’s one of those pieces you can throw on and still look put together.

Good value, soft and comfortable
Color: Black, Army Green, Light Gray, Size: 4X-Large, Color: Black, Army Green, Light Gray, Size: 4X-Large
Initial thoughts are very positive with this 3 pack shirt set. The green is similar to an OD military green and the black and gray are standard color shades. Material is soft and sizes are true to size. The mock turtleneck isn’t too tight but may still be a little annoying to some people. I do question the amount of spandex in these shirts. Tag says 5% but these shirts are extremely stretchy and feels like a higher spandex content. It’s also a little tough to figure out which way is the front of the shirt. Visually rhe front does have a lower collar line than the back but would still be nice to have a brand tag printed in the back of the shirt for quicker identification. Overall for roughly $12 a shirt these are a good choice for everyday wear. I will update rating if these shirts fail to meet expectations after further use.

Just what I wanted.
Color: Black, Navy Blue, Wine Red, Size: 5X-Large
These may have just become my standard shirt to wear. Feels good whether tucked or out. Drapes well and fits well. So far, I can see it adjust to the different undershirt I may wear. Will probably order another set in other colors and a back up set of the basics because they will get worn a lot.

Its alright
Color: Black, Size: 5X-Large
True to size per the size chart. The fabric is soft but it it feels cheap to me. It attracts lint but you can brush it off easily so its not the cheapest material I've dealt with. Also, it is opaque (not see through). There is no front/ back indicator either which is indicative of a cheap shirt in my opinion. Would be friendly for tag sensitive people (to stay positive).
