I am wondering, if I take the water and the filter and it's media from my current tank and use it to help set up a larger tank, will I still have to do a cycle period on the new, larger tank? It seems I read somewhere that if you use the water and the filter and it's media from the current for the new, you can go ahead and switch your fish over immediately. I plan on switching from current gravel over to sand or a substrate for growing plants, and new decor. I will keep and use the driftwood I currently have, also. Will it be ok to add my fish, and new plants, into the new tank as soon as I get everything switched and set up? Thanks for any help and advice!!
