Question: 90 Gallon tank cycle finished???? :D

[axiebeans]

I think my 90 gallon has finished cycling the nitrite went up to a whopping 2mg and I did a water change it went down to about .5 then went back up to 1.5 in a day. The next day it was only 1. The next day only .25 now 0 . Cant find the card for ammonia at the moment but I know the color is less than .25 just not sure how close to 0 it is but its got to be right there. Nitrates are at about 2 - 2.5 mg. Is it safe to assume my tank is cycled now?

A tank is cycled when it reads 0 for Ammonia and NitrItes and then your weekly water changes keeps the nitrAtes below 20.

You need to feed your tank ammonia everyday if you are doing a fishless cycle otherwise the bacteria will starve and die and youll have to do it all again

But once you can add 5ppm of ammonia and its gone to 0ppm in 24 hours then you can add your axies to the tank and your good to go
