I don't even know where to start. I was thinking last night that it might be a good idea to switch the two tanks I have now. I want the SW to be FW and the FW to be SW. I know I have a huge job in front of me and may take up doing it sometime this winter, but I just don't know where to start. Or if it's even worth the effort.... I don't know if I would rather just get a bigger tank for the goldies.... *sigh* what to do, what to do, what to do....
