How long for an FX5 to be fully established with BB?

  • We are currently upgrading MFK. thanks! -neo
Cool. I will probably transfer the existing FX5 to my 125 I'm setting up, with the gravel, and all fish too. Then I can use the HOB filter for the 55 and put some silver dollars and bala sharks in there to get the tank flowing again with the new FX5 and start building some new BB in that one. Thanks!
