Going from a 10g to a 33g tank, what will need to be changed?

  • We are currently upgrading MFK. thanks! -neo
you should put the mollies in the tank, slowly raise the salinity, and acclimate any new fish when you buy them.
i know that is you switch a fresh tank to a SW tank you need to re-cycle the tank. i don't know if this is so for fresh to brackish.
