I'm cycling my new 150 gallon tank. Its been up and running since last Friday night. I was wondering when i could add fish and how I can tell when its ok to add fish. I did a water test and ph- 7.2 ammonia- .25 nitrite-0 so I don't plan on adding fish for 2 weeks at least but is that long enough?? I added rocks and drift wood from my setup tank to help the bacteria start growing. And also I will be adding my filter to the new tank which already has a cycled Bio wheel for extra filtration.
