Most test kits are priced much higher, if you are on a budget this kit will do just fine. It is easy to use if you can follow basic directions and are not color blind.

great solution for monitoring your tank parameters. accurate meters also. the price here cant be beat. i'm so thankful that i can get a deal here. but yah, this product is great- a must have if you want to keep an eye on your water to keep your reef smiling.

Use it to maintain my 55g reef tank. Very nice test kit. Easy to follow instructions. Easy to perform tests and assess results.

Would be an excellent kit. However, mine did not come with color charts. Called API. Supposed to get in mail. Also, this kit is needed in conjunction with saltwater test kit. Wish it was one complete set.

Simply put having a test kit is essential for any reef aquarium keeper. I only have a 28-gallon tall aquarium with just soft corals, a feather duster, a few damsels & a couple of cleaner shrimp. The API Reef Master Kit is well packaged and everything is labeled very clearly. I sometimes have difficulty interpreting the nitrate and phosphate tests as the results are limited to viewing color code charts of different shades of green and orange. For example when I conduct the test for nitrates, my resulting shade of green from my test tube is in the range of .50 to 1.0 as my best guess instead of .50 or 1.0.The instructions are very well written and easy to follow although I can't help, but notice API's intentional attempt at product placement by their brand. For example if your test kit yields a high result for phosphates, the instructions recommends that you purchase & use API's Phos-Zorb to help reduce phosphates in addition to conducting water changes & removing waste. If you have low calcium levels you can use API's Eco Calcium Marine to increase calcium levels. If your nitrates are high you can use API Tap Water Filter to help reduce nitrates in addition to water changes & the removal of waste.Some other reviewers have complained about the absence of the ammonia test, but I have already owned API's ammonia test kit (with its different shades of yellow test results chart) that I used when I initially cycled my aquarium, so adding the reef master kit just supplemented to what I already have. Didn't need the instructions help to buy another API product for ammonia testing because I already did.Overall an adequate test kit for the very important task of truly knowing what's in your aquarium water (or at least ballpark figure ranges) to help your corals, fish & invertebrates thrive successfully.

Has all the supplies you need and a case to keep it all in. I wish it had a quick instruction sheet for all the tests. The instruction book is very detailed and the testing is accurate. Highly recommend for testing your reef tank. A must have.

nice price (few bucks less than LSF) very easy to use, booklet explains eveyrthing you need when starting a tank.

Fast shipping. Very easy to use the tests. Seems fairly accurate. Test for common reef parameters, I bought the saltwater test kit too

I saved a lot of money over buying these from the local pet stores which most of the pet store chains dont even carry Salt Reef test kits, I got the kit faster than I expected, it was exactly as advertised and I consider it a must for the reef hobbyist. Especially a new one like me.

Ok lets start by saying the description is wrong for this item. These are not the chemicals to measure for the nitrogen cycle (except the nitrate) the others are phosphate, carbonate hardness, and calcium.API test kits are notorious for being inaccurate, though I disagree with that sentiment it's more likely people let their tests expire. Although you get what you pay for. This is a very inexpensive test kit but the tests do work. I do suggest using Red Sea or Saliferts over this test kit though. For phosphates I'd rather get a Hanna Checker Colorometer though much better than trying to distinguish vague color variations.

this item came very well packaged. i am very pleased wit the overall prdukkt ya did i mean nnnn n

This kit is a reliable test kit, however, it does not come with testing material to check PH balance and Ammonia. That's the only downside to the product. Instructions are straight forward and the kit is a REQUIRED tool for any saltwater aquarium.

This is a good kit for a quick check, just keep in mind that some of the result may not always be correct. There are a couple of tests in this kit that are not accurate at all. The mfg. even sent us another kit and we ended up with the same results.It is good and cost efficient for general checks, but best to take your water in to an good aquarium store now and again if you want to ensure accuracy or suspicion something is out of balance in your tank.

this works very well and is accurate and helpful. and its for an amazing price lllll

I have always used brand api in marine gauges are always very cheap and are really high quality 100% recommend

Test kit is easy to use and gives seemingly accurate results. I feel like a scientist when I use it.

I have been using this a lot because my aquarium gives me fits. It seems to work well. Everyone suggests more expensive test kits but I don't see why. this one works fine for me.

I love my kit, very fast on delivery of my Kit. I got both the Reef Master & Saltwater Kits, they work great for testing my water.Thanks

I'm sure there's many test kits out on the market. This bare bones tester does fine and measures everything I want it to measure.

In all, a good product. It is not a comprehensive product, but as is advertised and is invaluable for reefs. Very satisfied.
