Hubby suprised me with a new 36g corner tank today. Now I need to figure out how I am gonna do the old switcheroo. I currently have a 16g bowfront with a hob penguin 100. Have a rena xp2 to put into the new tank. Do I put my old mech. filtration (carbon cartridge) into one of the media boxes? I am hoping to move all my gravel, decorations, plants and fish into the new tank as I only have room for one in my living room. I have 4 neon tetras and 2 cories in there right now. Should I expect a cycle if I move all my stuff and old water into the new tank? I plan on moving my old tank to a different room to use as a quarantine for my new fish I will be getting to fill out my schools. Do I need to do anything to maintain my cycle in the quarantine assuming the great switcheroo goes well? Thanks in advance!
