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?
