I just finished setting my tank back up after a rebuild. It's cycling at the moment but the filter wasn't cleaned, just disabled for a few days. I'm wondering if I can start the tank up and rely on the filter(which already has established bacteria) to cut my cycling time in half.
Yes, the old bacteria should seed the aquarium quickly.
However, i am curious as to why this process took place to begin with. Did you move? Was there a problem you were attempting to correct?
I ask for a simple reason. If you are concerned about seeing a biological filter, this tells me a lot of information about your setup. Primarily, you are using a filter that is designed to intentionally introduce Nitrate into the aquarium. Why?
