My api test kit bottles leak every time I shake them for the nitrate test are the faulty or is this normal because I do not want to poison my fish or myself via my hands that are covered in test chemicals. -
Has anyone found a better cap for the API test tubes? There's a lot of capping and uncapping for the two part and titration tests that it actually starts to hurt my fingers. Frankly I'd take a cap that doesn't even hold itself on and just pinch the cap down when shaking over how tight these are.
