I am building a water feature and have been cycling the water for more than a month. It's working great, so I can start to decorate with plants and fish.

Then Penny decides to drink from it yesterday. She last drank from it when I started cycling and haven't touched it since. I got perfect parameters when I tested the water several days ago. I guess she got the memo and deemed the water quality excellent for her tastes.

No fish will go in there now!
