Fresh!
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.

Did it was supposed to
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 Iâve been doing so for over a month now.

Very good product, it does its job
i was very upset when this product arrived because it was leaking through the box, literally DRIPPING. once i got over the fact that i had lost alot of the product, i began to use it and it does make a difference if used regularly and regimen maintains consistent. This product is nice because it does have a sufficient concentration. but since ive purchased, ive switched to Dry ferts and they provide more effectively, in my opinion. but flourish Iron is still a good product, if its shipped properly

Noticable difference
I have amazon swords from a chain store. Not always the best quality but the price was just too good to pass up on.There was noticeable discoloration that couldn’t be attributed to them being in a new tank since that time passed. I started using this in conjunction with some DIY root tabs and wowie! I have plants that are strong and giving off new leaves quite often.Seachem is the gold standard.

Seachem stuff always works!
Seachem is my personal go to company for the few chemicals that I use in my tanks, I usually Seachem stuff always works! I however only use half the dosing, adding the second after a few days, not a fan of nuking my fish.

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

Good brand and quality products
John young brand –
Essential product for planted aquariums for sure, if youâre looking to have any success with this particular part of the hobby.
Nice tools –
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.
