So, I have been offered a Marineland Pro 300 gallon for a price that is simply too good to ignore. This is far from a sure thing, because I still have to get approval from the wife - but there is all kinds of stuff I learned about this hobby that I had wished I had known when doing my current setup, and I'd love the chance to do it over again.\r\n\r\nThat being said, if I do go forward with this, I have a 180 full of livestock that would need to be moved. Is the general jist of the process to save the tank water from your current setup, and use that along with newly mixed saltwater? \r\n\r\nI assume as you take down the current tank, you just throw your fish in rubbermaids with some of the live rock, and possibly a heater? \r\n\r\nThen you save as much water as possible for hte new tank, put in your live rock (and corals) add your sand, finish filling the tank, and then add the fish in?\r\n\r\nHow likely is a cycle? Is it possible that fish will be lost as part of this process?
