Can I use multiple testing strips in a cup for testing sn?

[iwantitalltoend]

I want to use a few aquarium testing strips from different brands to see if there's a difference in results. I'll use 2 cups of 1 l of distilled water each, I'll put 5 g of sn in cup 1, take 2 ml of water from cup 2 and throw it away, then put 2 ml of water from cup 1 to cup 2. I was wondering if I can use more than 1 testing strips in cup 2, so I'll put the first strip, see the result, then the other ones in the same cup. Is it ok or will using more strips in the same cup affect the results or contaminate the water?

After you prepared the solutions according to the guide you want to use several different test strips with that solution?

That isn't an issue, you can actually test the water an aquarium with different test strips from different vendors, too.

Edit: The test strips don't contaminate the water.

Yeah I want to test the same water with a few testing strips from different brands to see if there's a difference in results for the nitrite levels

I don't see a problem in doing that.
