What would I use to test if 3% H2O2 is still potent?

3% is 30,000 ppm, so NOT these 0-100 ppm test strips! You need Very High Level 2-10% test strips, which are available on Amazon.

While this product be able to measure a 7% solution of hydrogen peroxide?

This product will not be able to measure that high of a level of hydrogen Peroxide. What you should get instead is the Bartovation Food Grade Time Sensitive Very High Level Hydrogen Peroxide (h2o2) Test Strips, up to 10% Concentration (ASIN: B01CDX4ZB6). Those strips will help you know if your solution is approximately 7% because it will give you a reading in between 5% and 10%. Please let us know if you have any more questions or if there is anything else I can help you with! Best, Scott

How do i test 35% food grade hydrogen peroxide with your test strips. what ppm would i read on the container. what would i read if i reduced the 35%?

This product is designed to test residual (low level) peroxide, so, although it could be used to test food grade hydrogen peroxide, it would require a very precise dilution ratio that would be hard to achieve accurately. For testing food grade peroxide, I recommend using our "very high level" strip (https://www.amazon.com/dp/B01CDX4ZB6), where you would: mix 1 part 35% peroxide solution with 2.5 parts water to yield a concentration of 10%. If the color change is not immediate, then the initial concentration was not 35% (or a mistake was made in the dilution). Try other dilutions to zero in on the actual strength, e.g. 1:6 should give you 5%; etc.

I bought these for my pool, after putting 5 gallon of 35% h2o2 in a 25000 gallon pool water, the strip turns black, what does that mean?

As far as I recall the amount needed is 1 cup peroxide for every 250 gallons. Black is probably way higher than shades of blue that can register on strip; probably over 100 ppm.
