Sure! Throw that in my face! ;-) Otoh, if you dose a bit, say, with a good trace mix like Flourish or TMG, then you know the tank always has some and you don't need to test at all. Okay, I don't mean to be flip. Here's my case: My tap water is as clean as a new baby's dreams -- pH 7.0, barely any carbonates), etc. So all the iron in my tanks come from the Flourite or from the trace mix. I haven't had iron deficiencies show up. I have tested to confirm the iron levels -- what gadget haven't I bought? ;-) Actually I bought the Hach kit to test the levels in two 20g tanks I set up for substrate comparison, one with Eco-C and one with Onyx Sand. Since I had the iron kit, I checked all my other tanks, why not? What else am I going to do with 100 iron tests? I've tried supplementally dosing iron on top of the trace mix, assuming that with all the iron some folks put into their water, I must be wrong about mine plants. But I haven't seen that it makes a diff in the plants -- but then I really didn't see an iron deficiency to begin with so I wasn't too surprised that I didn't see it improve. For those on a budget, I'd recommend *not testing for iron at all* unless strong suspicions of an iron deficiency need to be allayed. And then, I'd probably recommend making sure the traces are dosed at the recommended rates or a little heavier rather than trying to test for iron. And then, if I *still* had doubts to assuage, I might get a cheap kit just to confirm that iron is present. If I wanted to know how much iron was in my tanks, I'd want a good low range kit but I think it's an unnecessary luxury for most folks.
