I loved the fact that I got my item in two days when I feared it would take eight days according to the plan I purchased. The product is simple and quick to use. I think that the pet shop where I go in town has the same test equipment for the aquarium water and that makes me feel secure. I will order from Pet Mountain again.

A must for anyone serious about the care of their fish. Comes with the basic test necessary to ensure a healthy aquarium. You will not find this test kit anywhere for the price offered by Pet Mountain.

On April 10, 2012:
This site had the cheapest price for this product. Excellent shipping.

On January 10, 2012:
This is an excellent test kit. Provides all of the basic test for a freshwater aquarium. Test are easy to perform and easy to read with the supplied chart and instructions. I consider this a must to anyone with a freshwater aquarium.

I needed a new test kit. A fellow aquatic frog enthusiast recommended Pet Mountain. Great deal on a basic everyone with a tank needs.

On October 18, 2011:
I saw this same test kit in the pet store for TWICE this price, and that was still cheaper than buying each type of test separately, so this is an AWESOME deal! Comes with detailed instructions for each test, a water-resistant card to check your results, and each bottle has a bold number on it that lets you know how many drops you need to use. The kit also comes with enough vials that you can do multiple tests at the same time, and they have flat bottoms so you can stand them up on a flat surface or use the spaces in the test kit base to hold them if you prefer.

I've read that liquid testing kits were the way to go in the long run. They're more accurate than test strips and cheaper overall because you get more tests from the liquids than you do the strips, therefore you have to buy strips more often. Everywhere I've looked, they've had the kit at around $30 and of course it's even more with shipping if you order it off of a website. I found this when it was on sale ($17.90!) so even with shipping it was still waaaay cheaper than anything I've ever seen. The only problem I have is the way the box is designed. It has an instruction manual and a thing to compare your results off of. You put it on the sides and the lid goes over it.. Usually when I open or try to close the box, the papers on the sides end up falling over for lack of support. It's not hard to close, it's just obnoxious. Otherwise, the kit works VERY well and should be recommended to any fish/aquatic owner, especially for someone who has a tank large enough to support the nitrogen cycle. So it's not the product that has problems, it's just the design- thus giving it a 4 star rather than a 5. Otherwise, it would've been perfect.

I ordered this text kit on 6/22/11. I was so excited because this kit is 30+ in stores and after shipping it was 23.99 from pet mountain. I received it today 6/27/11 from my mail man! I could not be happier with the product (I love API)! Not only did pet mountain save me at least 6 dollars plus a trip to the store, but the processing time was incredibul! I used the saver ground which is 5-8 buisness days and received my product in 4 days including the day I ordered it! Thank you Pet Mountain! I love the freedom to test my water at home instead of taking it somewhere!

Excellent Fresh water test kit, very glad I bought this. Has all tests needed for establishing and monitoring a fresh water tank. Easy instruction and easy read result chart. Test kit is great for monitoring water cycle at start up and monitoring existing tanks. Bottle has child safety lock caps (TIP- easy adult open if you read the instructions on bottle ) Pet Mountain had a great price & very fast standard shipping.

On March 8, 2011:
It tells you to shake the bottle of test solution for the nitrate test vigorously for 30 seconds before adding the drops to the test tube... But ALL the bottles the test solutions come in, leak. ??? Can we design a better bottle/cap?

Strips are hard to read with that little dot to compare. The vial test is is a lot easier to compare and there are A LOT more tests per container than a pack of strip tests!

PS:Wash out vial after use! It might stain the glass up a bit causing you to need replacements.

On November 1, 2010:
This is a totally convenient, easy to use kit. Makes taking care of the tank easy and you smart!

The API Fresh Water Master Test kit is an invaluable resource to fish keepers. Know exactly what's going on with your water fast! It helps me stay on top of water changes, and takes the guess work out of testing. No more test strips for me!

On July 13, 2010:
This is likely the most highly reviewed and recommended test kit, and covers almost every test you'll need (should definitely cover all the testing needs of the beginner to intermediate freshwater fish owner, though you may wish to also purchase water hardness or one or two other individual kits separately, depending on your aquarium needs).

Add to this that the price of this one item alone is so low that even when combined with the cost of shipping is still cheaper than picking the same kit up at my local stores, that makes this an unbeatable deal for me. I'll save myself some time and gas money and order from Pet Mountain!

On February 4, 2010:
Great kit for the price. Very accurate. Carefully follow instructions to ensure your NITRATE test is accurate (requires vigorous shaking). Currently fish-less cycling a 60gallon so this kit is used daily. Quick, easy, accurate. Two thumbs up!

On November 22, 2008:
Takes longer than test strips, but definitely more accurate. The Pet Mountain prices are the best deal on this test kit! I gave it 4 stars because the regular pH test solution needs to be shaken extremely well because it precipitates heavily on the bottom, and tend to make all my initial readings run very high. I wasn't able to get it to give me the same readings as the LFS, which uses a similar test, until about the 4th time I used the solution. If it weren't for that, I would give it 5 stars! I have freshwater and saltwater tanks and have been able to successfully use this kit on both tanks. The only thing is the salt causes some of the solutions to precipitate a little in the test tubes, but the colors are still easy to read. Mainly, I just use the high range pH for the saltwater tank with no problems because I have a Reef Master Kit which takes care of my other needs.

I have found some great deals on many items!

On January 21, 2008:
This kit is so very easy to use. A lifesaver when cycling a tank and just for ongoing tank maintanence. I use it weekly to help me know when i need to do a water change. I like my fish to thrive not just survive!!

good site

On September 3, 2007:
The Test kit is just want I was looking for. This test kit is so easy to use. I love that on the back of the test cards there is "how to do the test"
Great Test Kit!!

On August 31, 2007:
very good value here - I've seen the same kit for $30 and more in pet stores. It has all the most important tests for your aquarium. several more test tubes would be good, though.

On August 29, 2007:
This is a great product! It lasted me a long time and seems to be the only one that can measure ammonia, essential for cycling info. Thanks!

On July 29, 2007:
A good test kit, it comes with all the tests you need to start a freshwater aquarium. However the nitrite test can be kind of finicky and one of the test tubes leaked.

On July 23, 2007:
Awesome, easy to use kit. Highly recommended

On June 13, 2007:
This testing kit gives accurate results and provides clear, easy-to-understand instructions for use. In addition to the more detailed instructions written in the booklet provided, illustrated directions are included on the back of each color card for quick reference. This kit was also the least expensive testing kits I could find.

Highly recommended!

On April 24, 2007:
This kit is very affordable and very complete for regular people like me. It's very easy to use and accurate. It tests the most important parameters for your freshwater tank.

On April 7, 2007:
The ammonia &
Nitrite are spot-on each time & almost identical to the colour cards
supplied so they get used all the time. The 2 I have a problem with
the high-range pH because the colour it displays is unlike any of
those on the card. Similarly the spectrum of colours on the Nitrate
test card are so similar it's impossible to tell if your reading is
anywhere between zero & deadly!

On March 28, 2007:
Whether you use test strips or chemicals, API's Master Test Kit for Freshwater/Saltwater is the best by far. Check any good fish forum for consistently-validated superiority. The cheapest and the most accurate.

On March 13, 2007:
This is the best and most accurate you will find anywhere. It's very easy to use and gives awesome instructions.
