And use the test for general purposes ONLY. Iodine test kits for sw aquariums are iffy at best.
I do not recommend dosing iodine at all if you are doing proper water changes. Salt mixes have an adequate supply, and you don't have the load in your tank to require it. Overdosing iodine is lethal.
Trace elements are in your salt mix. No need to add any until you have a lot of stock, and even then most reefers don't add.
You should be testing for the 4 big ones, plus calcium, alkalinity, phosphate, and to a lesser extent magnesium.
