Nice! I thought for sure that I perhaps some massive destructive population of creatures. Nice to know that if I do they aren't them!
I purchased the Master Kit and did my own testing.
Ammonia: 0 ppm
Nitrates: 0 ppm
Nitrites: 0 ppm
I am guessing that my added base rock didn't start a new cycle. I added a bag of activated carbon in place of about half the Bio Balls just in case there was some unknown toxin in the tank from an air freshener, windex, etc. I discussed with the family the importance of not using any chemicals near the tank (just in case).
I still plan on leaving it vacant for bit.
I will keep you all posted. Thanks for the help on this!
