Do these work for saltwater aquariums?

This test is most likely not sensitive enough for Marine aquariums. The lowest detection level is 0.5 ppm as N (as nitrogen) which is the same as 2ppm as NO3 (as total nitrate).

How many strips are in the bottle?

Over 50. The manufacturer always puts a few extra over 50 in each bottle

how many ppm do the test strips have?

NO3: 0, 0.5, 2, 5, 10, 20, 50 ppm (mg/L)NO2: 0.15, 0.3, 1, 1.5, 3, 10 ppm (mg/L)Total Test Time of Less Than 1 1/2 MinutesHope this helps!
