So I have a week and a half old tank that I had set up for the first week with out fish. I added a pinch or two of fish food to try and āfeedā the bacteria I added with API quick start? I never had any kind of water chemistry changes. And after having the fish in there for 4-5 days now, all of my levels are still staying the same. I have done one 30% water change just to make sure every one was healthy and happy. I was just wondering if this was normal. I feel like Iām just going to wake up one morning and something will have gone terribly wrong and my 4 doh are going to be dead. Help?
