I have 2 tanks currently but my daughter who is 5, wants her own "fidges"
I'd like to get her a small tank - 40-60L.
The question is this - I regularly remove and dispose of more than 60l from my other 2 tanks when I'm doing their water changes. The fish are all healthy and both tanks are 0/0/10(ish) when tested with the API kit.
Could I use this water to fill my daughter's new tank? Will it still need cycled? I know the filter will need to grow bacteria in its own media, but will it take long?
Just a thought. I'm happy to start fresh again if that's the best idea.
Thanks in advance.
Richard.
