This explains it. I don't have the Red Sea iron test kit, but their other
kits (with the possible exception of pH and ammonia) have given me nothing

The Sera test definitely works with chelated iron, or at least it works
with whatever (DPTA, etc.) is in Tropica MasterGrow. If you give it 3-4
hours it works, but the response after 3 minutes is negligible.
I verified this with a semi-scientific experiment where I created diluted
solutions of TMG and Flourish with the same approximate Fe concentration.
After 3 minutes, the Flourish sample showed the expected red color while
the TMG sample was nearly clear. After 3 hours, both were nearly identical
I'll have a write-up and pictures on the Web shortly for this.
