My 29 gallon aquarium sprung a bad leak last Thursday. My husband rushed to get the water out while I rushed to save the fish. I have had the fish in a small 2 gallon tank for a week while we cleaned up the carpet and finally set up the new tank. The new tank has been running for a day and one night. I added a few cups of the old water to the new tank to speed up the cycling process. How long do I have to wait to add the survivors back in the new tank. I don't want to keep them in the small holding tank too long. Will a few cups of the old water be enough? HELP!
