This is much more worth it than the test strips. Super easy to use! Comes with clear instructions! One of my tubes did break eventually after using it a lot but you can get replacements online (glass or plastic ones).

I purchased this on recommendations of others. It arrived promptly and as advertised. These tests are essential for the health of your aquatic creatures. Pros: The instructions are simple to follow, and results are easy to interpret. Everything is included for these five tests. Cons: Only four test tubes; plastic tubes, no syringe for filling tubes. Advice: I purchased a 5 ml bulb syringe (made for giving medicine to babies) to fill the tubes easily, and a 24 pack of test tubes from API. Now I can do all 5 tests without reusing a tube, and I'll have enough extras to cover a lifetime.

I've been battling a turtle who has excessively been shedding skin. I suspected high ammonia levels in his tank. I purchased a couple of different paper test strips and got conflicting readings from no ammonia to moderate. My vet recommended this test kit for it's accuracy. OMG, the ammonia level was dangerously high. I am so thankful to have purchased this test kit. I highly recommend it.

This is a must have when starting a new aquarium. You gotta get that water right and be ready to fend off an ammonia or nitrite spike. Wish they had replacement chemicials so you don't have to but a new kit everytime.

My only complaint with this test kit is the phrase "Masters Test Kit" very much implies it has everything you need for fresh water tanks. The problem with that is that it is missing kh and gh tests. Those are very important if you want to own invertebrates in a tank and even outside of invertebrates there are times you would want to test it as well to make sure the tank is relatively balanced. With that said it is the only test kit I use even though I buy my kh and gh test kits separately in the times I do need to test it and the reason being is the test kit is very accurate for testing the water. Normal test kits like the ones that use strips are nowhere near as precise as this test kit so it makes up for the previously stated flaws. If you plan to keep invertebrates in your tank you can buy the necessary chemical tests separately and other than that this is a great beginner test kit for aquarium enthusiast. Thanks!

I used this kit years ago when I kept tanks. The only difference is they now come with plastic tubes instead of glass tubes. Fortunately, one of my local fish stores sells the glass tubes made my API.

These kits are more accurate for testing water parameters than any test strips. Please use them instead.
