REEF MASTER TEST KIT Reef Aquarium Water Test Kit 1-Count

Great basic test kit, fairly easy to read results. A couple of the tests can use quite a bit of drops and I wish they were bigger bottles but at least they can be purchased separately. I find that the less I mess with my tank the healthier it is. This helps me keep an eye on things:)

I'm a reef novice. This is a great reef aquarium test kit for beginners. It's very easy to use thanks to the detailed instructions that educate you on what each water parameter affects in your reef aquarium, and you don't even have to convert any units of measurement when using it. So far I've gotten accurate readings. I'm very satisfied and will continue to use API products, particularly this water test kit.

Good product.

Buyer beware, these online kits (particularly the KH) is inconsistent and severely in accurate when compared to those bought elaewhere. I bought this 4 test reef kit in large part to monitor my KH. I very early killed my reef because the include KH testing solution is very diluted. A few days before my kit arrived my local fish store measured a dKH of 9.0 With a goal of 10-11, I added some buffer equal to what it took to go from 8 to 9 dKH. Boy was I surprised when I reached drop 17 and it still hasn't change color at all. Tested multiple times after a couple of water removals, the lowest read I got was 13 dKH. The exact same water was actually 8. This was done by using his own store bought API reef kit. The worst part is that Amazon does not allow returns of this product, and there's no way to swap out this one bottle because there is no 3rd party vendor I'm directed to by Amazon to discuss replacments, nor any person or place to complain to about this faulty equipment (except by writing this review). ------------ Update: I found the place to talk with amazon about this item, and the issue has been resolved because they'll send me a replacement. So on the one hand you may need to double check the strength of reagenta with a friend's reef kit - but Amazon is actually pretty helpful and generous when you are finally connected to a real person on the phone. So, -1 star for this bad KH testing batch and the near miss to my tank ecosystem, but that still leaves 4 stars for this kit that is great for the beginner hobbyist. Good luck!

Works great, my husband uses this for his saltwater tank at least once a week!

this is the second kit I have bought from this manufacture, was very happy with first one and still am with the second. it is very simple to use with simple instructions, the readings are accurate . we use this for out 125 gallon tank with fish, live rock, and corals. always ships quick and at a good price that beats the stores.

I had bought these just to see if my electric devices were accurate and these seemed to be more accurate so i now prefer to use these over anything else

I love testing my reef parameters, however I like to minimize my exposure to chemical that are "suspected of causing genetic defects," as the Nitrate test bottle heeds a very scary warning... The phosphate test label reads "suspected of causing genetic defects, will burn skin and fatal if inhaled." There's no caution when using these and I didn't even wear gloves until I noticed and read the labels!! The caps on the little vials are very dangerous because when you fill the vial, add chemical, open the vial, chemicals drip out of the cap and down the side of the vial. Then you add your second chemical, shake the vial for 60 seconds and you're flinging this chemical across the room. I feel sorry for the guy made a "how to" video for using this test kit and has the chemicals dripping all over his hands... maybe that explains the arm growing off of his neck... Since I'm very scared of these chemicals and they're warnings, I don't test as much any more. Every test I performed seemed accurate!
