So I'm downsizing from a 100 gallon to a 65 gallon aquarium soon. I may have the option of having both set up simultaneously for a short time if I decide to put the new one in a different location in the room, but I'm not sure yet.
Either way, how would you all make the switch? Here's one plan I've thought of:
(1) Put fish in the sump with a powerhead (they'll have plenty of room)
(2) Fill a tupperware thing with some of the water from the tank and put all the rocks and coral in there with a powerhead.
(3) Put new rinsed sand in the new tank and fill it with the rest of the water from the old tank, give it a little starter from the old sandbed.
(4)Drag my sump with DSB from the old tank and put it under the new one and reconnect all the plumbing (hopefully won't disturb the sand bed too much).
(5) Put the rocks and corals and fish in the new tank with the old water, top off with new water and start up the circulation.
I figure this way the only thing that is "new" as far as fish and coral is concerned is the shallow sand bed which would have to cycle.
Any other ideas or comments?
