Is Tetra test strip reliable?
Especially I need it on NH3 and NO2.

Thanks.

In a word, no. They are terribly inaccurate and also very expensive. For what you pay for a 50 pack of the 5 in 1 strips (I'm sure that's not what you have or are talking about because the 5 in 1 don't measure ammonia), you can get an API liquid master kit that will do100 to 200 tests.

Test strips are not always the best plus they can be very expensive. Where as buying a liquid test kits will save you more money in the long run, and they are usually much more accurate.
