What would be the best guess as to how Long and how high a cycle I would get from the following: The complete removal of my current live sand bed from my current tank, that sand moved to another tank with the additional (store bought) live sand added to the new tank. All the current live rock would be moved and all the current water would be transfered to the new tank. Additional fresh saltwater could be added or the saltwater could be circulated with the current tank water and then added to make up the 50 gal differance. Thanks.
