 I finally got an Iron test kit (Sera)... I tested my water and it showed 0
 mg/l so I added some Tetra Flora Pride...waited 12 hours and retested... got
 a 0 mg/l .... added some more... tested a few hours later and it still shows
 up 0 mg/l!!!!  Whats the deal??? >>

What is the range of the kit?  Perhaps it is not picking up the low level
that the plants need?
