inherited a tank, fishless cycling now

Hey Ngmcmil,
Sorry I was busy getting rid of all the spam every day. I missed your last question.


Please correct me if I am reading your post wrong.
If you have no fish now, and you are doing a fishless cycling again, it will take a while for anything to change. When I did a fishless cycling for the first time with no heavy seeding of bacteria, it took more than 3 weeks for any reading to start changing. Even with heavy seeding, it should take at least a day or so to see ammonia dropping.

Please make sure to test it again to get accurate readings.
