I recently bought a tank off craigslist, cycled it, and added fish. Now that i've looked around at other peoples tanks I notice that the glass on my tank isn't very good, there are scratches and the sides almost look milky as you look through them. I want to switch to a brand new tank but use everything that is currently in my tank, what do I need to do? Can I just get the new tank (make sure it's clean) add everything from my old tank (sand/rocks/filters etc.) and immediately put my fish in there? I was thinking I would use a rubbermaid tub and add a heater and airstone for my fish while I'm doing the switch. Any suggestions? I'm mainly concerned about starting a mini cycle and don't want to put my fish through that but I have nowhere else for them to go while I do this.
