## Questions & Answers

**Q: Does this work for root feeders like Amazon sword? If not is there any iron supplement for root feeders?**
A: Good for iron deficiencies also but like previous answer go for root tabs

**Q: After treatment how long is the iron effective in a 125 liter aquarium?  How often should I use and does it stain the water?**
A: Best practice is to monitor level with iron test kit. The rate of consumption will vary depending upon the iron consumers.The level at which iron is safely added will not color the water or stain silicone etc inside the tank.

**Q: Anyone use this to help grow cheato? Results?**
A: If it consumes the micro nutrient iron faster than can be replenished properly with a macro nutrient supplement, sure. Test your levels- always.

**Q: Use in saltwater?**
A: It can be used in any aquarium

### ⭐⭐⭐⭐⭐ Work perfect

Excellent product!!

### ⭐⭐⭐⭐⭐ Good value
*by ***** on May 30, 2024*

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

### ⭐⭐⭐⭐⭐ Fresh!
*by N***A on December 31, 2018*

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.
