Flourish Iron 500ml

If you keep red or iron-hungry plants in your aquarium, this supplement can make a noticeable difference. Seachem Seachem Flourish Iron is easy to dose and integrates well into a regular fertilizing routine for planted tanks. After adding it consistently, red plants tend to show deeper coloration and healthier growth. The liquid mixes quickly in the water column and doesn’t cloud the tank. It’s especially useful for planted aquariums with species that demand extra iron to maintain their vibrant red hues. A little goes a long way, so the bottle should last quite a while depending on tank size. Overall, this is a simple but effective supplement that helps bring out the best color in red aquarium plants and supports healthy plant growth. Definitely a worthwhile addition to a planted tank fertilizer routine. 🌿🐟

Excellent product!!

After adding this for about a week, the growth in my tank exploded! I think iron deficiency is a much larger issue than most aquarium owners realize.

Great stuff, keeps my red plants bright & healthy in my planted tanks.

Iron supplement for your plants. Red plants require more iron than most green plants, typically. This is a liquid supplement to add weekly or after a water change. There are instructions on the label for use but I do wish it was simplified like Aquarium Coop's Easy Green line, where they have a pump head on it that treats 10 gallons per pump. Anything that takes some of the guess work out is a win for me so because I prefer that product over this, it only gets 4 stars. Seachem Prime is a solid 5/5 though so don't get me wrong, I like a lot Seachem products, just not their fertilizers as much.

I have ordered this product again on Amazon (see my previous two stars review below) thinking that I am ordering from a different supplier - I needed it urgently and my local store did not have it, so Amazon was faster and I took the risk. I still do not understand if my two orders came from the same/different suppliers, but this time the product is very light greenish-yellow (perfectly fresh) and plants are doing very well. Previous review: The solution is dark brown, so there is mostly Fe (III) there. Plants need Fe (II), most of plants can not use Fe(III). These bottles are so very old that most of Fe(II), which is very light green, is oxidized to Fe (III), which is brownish orange. Have planted fish tanks all my life, I KNOW how the fresh product should look. While the bottles are closed tightly, oxygen from air can penetrate the plastic bottle's walls if this bottle has not been used for many years. This is exactly the case here.

Plants love Iron in both the water stream and at the root level. This delivers the water stream level.

I had a really bad iron deficiency that decimated many of my plants within in my aquarium with new leaves littered with pale coloration. Dosing Flourish Iron definitely fixed my problem, and I clipped/rid of the casualties after I saw positive results. Additionally, my ph is on the high end of 7.8, so the type of iron present in Flourish Iron works more effectively for my plants than Aquarium Co-Op did. I dosed 2 capfuls 3x a week, and I’ve been doing so for over a month now.

Plusieurs années que j'utilise ce produit et toujours satisfait.

Good brand and quality products

Desde que lo estoy usando, mis plantas han empezado a crecer a lo bestia. Tengo un acuario de 600 litros con casi 18 años, y con todos los productos que he usado, nunca he visto nada igual. Las anubias han empezado a crecer y crecer tanto que se salen del agua. Las criptocorynes crispatula igual, llevan un año plantadas y no crecían nada hasta ahora. En fin, todo lo que diga es poco. Y con tan sólo 10 ml semanales para los 600 litros de agua. Increíble. Indudablemente, a partir de ahora ya sé qué marca elegiré para mí acuario.

Essential product for planted aquariums for sure, if you’re looking to have any success with this particular part of the hobby.

I had several plants that were struggling and I do use Prime flourish but adding this and flourish Potassium has made a big difference. Colour has deepened and my pink/red plants are holding their colour too. I do t have a top of the line aquarium light so definitely feel this product has made a huge difference.
