Hi, so I did something very stupid and I’m just kicking my self. I am cycling a new aquarium for a Long Horn Cowfish. I have put filter media from my Porcupine Fish’s tank ( I like to keep some extra media in the filter in case I want to start up another aquarium ) and put it into the filter for the new aquarium about a week ago and everything was going smoothly. Today I decided to do an ammonia test and of course instead of putting the lid on the tube first , I picked the the tube up that had both solutions inside and it fell through the feeding hole of the aquarium top. I immediately took it out of course and did about a 50% water change. The solutions were not mixed with the water in the tube yet and looked to be at the bottom of the test tube at the time I took it out of the aquarium, but I know that doesn’t mean that none got into the aquarium. I am currently running to the store to get some more carbon. I have a carbon pad from the established tank in there currently, should I take this out or leave it in and add some extra carbon ? Is there anything else I should do ? Should I test pH frequently? I did do a pH test before the incident and one after and both tests read the same. I know this incident probably isn’t common but any advice would be taken and greatly appreciated! Thank you!
