Work perfect
Great test kit for my Helloreef salt water aquarium

Relief to Use
These are relatively easy to use and accurate. They are the same tests my LFS uses and my tank maintenance person uses. It is a great value for the money and a good accurate test kit for the average aquarium owner. My LFS still does testing once a month to ensure accuracy but this helps to catch anything going south with the tank in between maintenance visits.

Good for the money, tells you where your water quality is.
Work pretty well, not always the most accurate but if you know basically what you're looking for these work great. They don't always measure traces correctly, but traces don't mean much. Fast easy and gives you a good idea of tank water condition.

Good buy!
This is a VERY easy testing kit. The chemicals that arrived had an expiration date of 2018 so ample time to use the product. Comes with 4 test tubes, easy color chart for reviewing test results, and a nice (but flimsy) storage box to store everything when it's done. The test instructions are the only thing I would change. The directions are simple enough, just they are in a booklet with several other languages made of plain paper. It works but I can see the book not lasting very long since these are water tests and accidents do happen. I already have a few wet fingerprints in it from getting the water out of my aquarium and browsing through the book. They should be laminated like the color charts, perhaps a card for each test. No big deal but certainly an improvement. I would recommend this to anyone though as it is a bargain and the test kit is great.

Excellent kit. Great price.
My order arrived sooner than promised and in perfect condition. I know some have complained about receiving test solutions that were out of date but I have to say, my kit arrived with experiation dates of 05-18, that's 5 years from now, you can't beat that. The list only flaw is that it doesn't include an alkalinity, calcium or phosphate tests, I guess I can purchase those separately. The test includes 4 test tubes, a holder, easy instructions, a great color guide to compare to for test results and enough solutions to probably last you at least till the expiration date. This kit is well worth the money paid for it and I would recommend this kit to anybody. I also forgot to mention that some kits you have to use a powder but the liquid test kits like this one are very easy and quick to use.
