Seachem Laboratories Multitest: Iodine & Iodide Test Kit

Yes, I would recommend this.

Seachem Iodine Test

Pros: Easy to use

Cons: Difficult to read

While the test will get you the results that you need, comparing the color from the paper slip to the test solution can be difficult. A bonus is that it does test for elemental iodide.

No, I would not recommend this.

Difficult to use, interpret and reproduce results

Pros: Price

Cons: Difficult to use and unreliable

To start, one of the two reagents for the test has to be mixed fresh each time you want to test using two additional reagents supplied in the box for a total of 4 reagents just to do one test. Next, the colorimetric test strip has a color gradient instead of the usual set color values, so it's difficult to decided on an exact color. Not to mention, you only have 20 to 30 seconds to interpret the test before the results are invalid. Also, the test is unreliable since I did multiple tests on samples from the same water and got different values. Sometimes the test didn't even develop. Normally, I compare home test kits to ICP-OES results, but this kit isn't even worth it. This test kit is cheap and you get what you pay for. Iodine can be lethal to your fish, coral and inverts--if you want to supplement, skip this kit and spend the $$ on something worthwhile.

DOES WORK BUT NOT EASY TO READ

BEST WAY TO USE THIS KIT IS TO DO A TEST WITH THE SAMPLE OF 0.06 READING SENT WITH THE TEST KIT THIS WAY YOU GET A IDEA OF THE COLOR REFERENCE. JUST MAKE SURE YOU ARE READY TO READ THE SCALE ONCE MIXED AS THE RESULTS DON'T STAY ONE COLOR FOR LONG MAYBE 10 SECONDS THIS IS THE DRAWBACK I DO NOT LIKE. YOU CAN GET A FAIRLY CLOSE READING FOLLOWING THESE TIPS. IF YOU DON'T LIKE COMPARING COLORS THEN TRUST ME DON'T BUY THIS KIT

Simple and Easy

I have read the reviews and it seems people either love it or hate it. I have found this kit easy to use and have no problem differentiating the colors. This kit also comes with a control test which has a known concentration of .06mg/l which is important in being able to trust the test kit. Overall this kit is simple and easy to use.

TRUTH

This test kit is impossible to get a accurate reading. 8/6/10 CONS 1.) Test kit has light blue to dark blue to tell what your iodide is at 2.) Completely useless because as soon as you add the reagent to get the color reaction it starts to fade from dark to light blue 3.) You have literally 20 seconds or less to guess what color matches on the chart b4 the test sample goes colorless. Pro 1.) At least if your sample water goes blue it tells you have iodide in your water. My opinion don't waste your money. If your really want to dose iodide or iodine just do like 1 drop a day per 50g to really play it safe. I use to do 4 drops a day of brightwell lugols for my 50g and had my iodine read at 0.09 which is high. The story is since I dosed at small increments my fish and coral where still safe even if my iodine was high. Dose small and you'll be safe hope this saved someone from wasting their money.

Results hard to read

From all test kits I tried so far this one was probably the worst. First you have to make one of the reagents yourself (?). Then the results are really hard to read: the final color is a very light blue and the scale given changes from fsaint blue to very light blue, almost impossible to get exactly the resulting value. And the final color only stays "on" for some seconds, everything gest transparent in less than a minute.

Hard to Read Results

I find the test very easy to use, and I appreciate having a reference sample - but none of that helps since I cannot read the results. The color key is composed of various shades of light blue with very little contrast. Trying to find a match for any sample is just a wild guess, and gives me no confidence.

Great Test Kit!

I had an idea that my system was in chronic iodide deficiency and it proved to be true. It was half of NSW. This kit is easy to use and has made dosing iodide safe. Levels closer to NSW are getting tired corals new life. I would and will buy this product again.

Good Test Kit

Using the reference bottle enclosed the test seems pretty accurate. Always a good idea to test for things like Iodine before you dose! Lots of steps to test and hard to read the color as it's just a long fade of white to blue. Once you get used to it thought it's pretty easy.

Poor Product.

The Seachem Multitest: Ioding & Iodide Text Kit is very difficult to use. You must have distilled water to make the test chemical every time you test. Most aquarium owners have R/O water, which is noted as not being pure enough. I had a hard time getting any reading at all even with fresh distilled water. If you do get a reading, it is very very difficult to make out on the color chart. The difference in colors is very small. I would have trouble calling this kit usable, much less accurate.
