I have to share with people who will understand.

First indication of 0 ammonia, 0 nitrites, high-ish nitrates. (40-80ppm-ish? We just did a 50% water change 2 days ago.) It's been almost 4 weeks since we started. Of course the first week doesn't really count because I tragically overdosed with ammonia and it took 3 massive water changes to bring it down. But after that, things proceeded just as expected! Wow!

This evening I'll dose again with ammonia and see if it performs the trick again, and then probably this weekend, FISH! FISH IN MY TANK! WOOOOO!
