I'm planning on upgrading my Waterbox 40.2AIO to a Waterbox 50.3 AIO which i've had for 5 years. I only have fish in for now. Which is the best and easiest wat to do this? Can I use the water from my old tank? I was not planning on using the old live sand but I do have live rock and media that I was going to transfer over to the new tank. Is this a good idea or not? Thanks for any input and or advice on this you can give.
