Customers say

Customers overwhelmingly praise these test strips as essential for maintaining healthy aquarium water, highlighting their simplicity and speed as primary strengths. Most users appreciate the quick dip-and-read method that delivers results in minutes without complex procedures, and many rely on them for routine monitoring across freshwater and saltwater tanks. Reviewers consistently report using the strips for months with confidence, crediting them with identifying water issues before they harm fish. A small number of experienced users compare them less favorably to liquid test kits, preferring those for greater precision, though most find the strips sufficiently accurate for regular checks. Overall, customers consider them a convenient, trustworthy tool for responsible aquarium maintenance.

Don’t buy this. It’s highly inaccurate. Buy the master test kit instead.

Great

Wells great, I use these frequently; I just recommend putting the wet strip on something like a paper towel because the ink will bleed onto the surface you put it on.

Yes, I recommend this product.

Ammonia test cannot be trusted. Strip never changed color. I used an ammonia tester specifically, the results were extremely high. Maybe one day away from a dead fish.

No, I do not recommend this product.

As far as testing strips go, these are far more accurate than any other strip out there. Next best thing to a liquid test.

Yes, I recommend this product.

The cashier price matched an online price, but the guy didn’t want to get me a shrimp after 8pm cause he said it was late. He told me to come back at 8am :/

No, I do not recommend this product.

The essential tests for the aquarium take a minute. When I want to test for pH, hardness and ammonia levels a simple dip gives me some results in seconds and within a minute it’s done. I recommend this product for every aquarium owner from the beginner to the experienced.

Yes, I recommend this product.

Questions

1 - 3 of 3 Questions

Does it come with a chart or do I have to go online?

  1. It does come with a chart attached to the bottle that holds the test strips. You just compare your sample to the reference chart. 



What should the ph, gh, kh, no2 and no3 levels be?

    Can the API 5 in 1 Aquarium Test Strips 25 ct also be used to test pond water?

    1. Dear Staff, Ponds are simply large outdoor freshwater aquariums. Surely these are appropriate. Please provide some science to support your opinion of the difference between measuring the pH of an outdoor pond and an indoor pond in a glass box...
