Iodine Test Kit?

[thirty5]

Which test kit do you recommend? I want to start testing for the other trace elements in my water and dose if needed.

Thirty, the Salfert is about the best.

That kit is not going to work at all. First, it is not a seawater kit, second it does not detect anywhere near the levels in seawater. Iodine in seawater is~0.05 ppm.
