Yes, I would recommend this.

Be sure to check expiration date

Pros: Should be able to test iodine.

Cons: The product has a shelf life and could be after expiration date, or too close to expiration date of product.

Last two I’ve gotten in Oct 2020 expired last year 7/19, same time the last review of “GOOD TEST BUT REAGENTS EXPIRE IN 3 MONTHS” by Matto. Be sure to check your expiration dates on each bottle and outside box.

Good test but short expiration date

Pros: Easy to use and interpret

Cons: Short life span/Quick expiration date

I like this test because it uses a control and the results are fairly easy to read. The problem is that I received a kit with an expiration date 3 months later than when I bought it. So, it's not a cheap kit and it's only good for 3 months. Not happy about that.

This is an easy to use test with accurate results. My only issue is that the reagents expire 3 months after I received my order.

Nearly Expired Reagents

Pros: Easy to Use

Cons: Nearly Expired Reagents

I would expect expiration date to be a year out on a new test kit but unfortunately the shipment on Han 2019 expires in May 2019. I have a lack of trust bothering with West Coast shipments in future.

Iodine test kit

I recently started adding iodine to my tank along with a couple of other trace elements. This iodine test kit works well, is relatively easy to use, and relatively easy to read. If you are using trace (Iodine) elements, I can recommend this test kit.
