Instant Ocean Master Test Kit (includes tests for pH, alkalinity, ammonia, Nitrite & Nitrate)

Would not buy this kit again. My reasons ; 1) Kit comes with one test tube, so each test must be done one at at a time over a half hour to run all the tests. 2) Foil packets are ridiculous to deal with as compared to liquid. 3) Started a new tank with this kit, for what ever reason, got a lot of false readings, especially nitrate readings.lost a lot of expensive fish due to this. 4) Finally ordered an API liquid test kit, because the Instant Ocean one was showing nearly zero readings on all three tests after almost three months of trying to cycle. 5) When I tested with the API kit, it showed my tank was completely cycled, and the nitrate level was actually a bit high. Don't know why the Instant Ocean was so defective, maybe expired? Who knows, buy the API

I have lots of test kits and really like this one. The chemicals are in sealed foil packets for long life, and the comparator strips are tinted hard plastic instead of paper, which can get wet and fade. Kit comes in a sturdy plastic case to keep it all together. 20 sets of test chemicals are included and refills are available. Highly recommended.

This test kit is as accurate as other I have tried but it uses powered regents for all tests except for the Alkalinity titration test. I prefer the API tests that are more straightforward and quicker to use. Price per test is about the same either way. Comes in a nice plastic case.

I prefer the liquid drops as it's hard to tell when all the powder is out of the packet. Other than that it's a good product
