Is Red Sea Iron test reliable.

I just tested my water with the RedSea Fe tester and it reads that I have 0 ppm .I add Seachem Iron 2.5 ml as instructed according to Seachem's dosing chart.Should I be increasing the dosage amount or did I waste my money on the test kit?

I have not yet heard of a Fe test kit that is truely reliable (except perhaps one of those really expensive LaMotte ones). Maybe you could mix up some different Fe stock solutions (according to weight and volume) and then test your kit on those. If you do, let us all know the verdict.

I have no experience with the Red Sea kit, but the Seachem Iron test kit is a lot easier to use and is quite accurate.

I'm not sure why everyone says it isn't reliable... I did a reading with it and got 0, dosed Seachem Iron according to the bottle, waited an hour, did the test again, and got a .1 reading, exactly what the bottle said the dosing would add.

Consensus from reading 1000's of posts:

No.

And neither is any other Fe kit.

I have no experience with Red Sea products.

The only way to know for sure is to test your test kit. Determine from Seachem's information how much Seachem Iron to add to a gallon of tapwater to raise it to 0.2ppm. Then test the solution. Try with a variety of concentrations if you want - 0.1ppm, 0.5ppm, 1.0ppm.

If the test doesn't agree with the known concentrations, then it's not working.

My Nutrifin iron test kit passes this test.

That's essentially what I was trying to suggest.
