Hi, new to the group, so Hello.

I am 4 weeks into cycling my 55g. I have minimal readings for ammonia
and nitrites and 20ppm for Nitrates so hoping that I nearing the end of
this process. I have 3 fish in there who are thriving and having the
time of their lives. I have been changing the water twice a week,
doing smallish changes, around 10%. I have been told to take from the
top of the tank so as not to disturb all the helpful bacteria's forming
in the gravel.


I have just started cycling my tank less than a week ago. How often do
I need to do water changes and % percentage?

Thanks
