How long should it take for a used tank to re-cycle...for lack of a better word.
I got the tank on a saturday and had to wait a few days to put the tank back up. The next saturday it was up and running with the same rock and sand. I did not wash the rock, and only aggitated the sand in water it was in. The rock and sand were kept at room temps in the water.
I had the water tested 2 weeks later, only nitrates at 10 ppm
.....would this be fine to start putting fish into?
