Tank Cycling

[Zelda000]

hey, i have had a 30g that has been set up for about 3 months, i recently moved it into my basement and refilled it and added the chlorine out and some stress coat. my question is, due to the dirt and such left in the gravel from before will my tank cycle faster, i was hoping to put in a 6inch black piranaha next weekend, if it it safe to, at 40$ i dont want it to die, soo waht do you guys think

To check before you add any fish, add enough ammonia to take the tank concentration to 5-6 ppm. Then, 24 hours later, test for ammonia and nitrite. If both are zero, you are good to go.

If all you did was move it, and it was established(cycled), then it is fine to put fish in sinse you are using all the same stuff.
