does anyone know if the ammonia reagent in ammonia testing kits are toxic to fish? I managed to accidentally drop an entire tube of water i extracted to test with the reagent, which i had just added to the test tube, into my 20G. the markings on the outside of the reagent say toxic, harmful if swallowed. it's been about 5mins, and the fish and inverts don't seem to be reacting adversely. should i take them out and relocate them just in case? advice welcome! thx
