I transfered my livestock from 120 to 180 on Wednesday.
I first transfered all the corals to containers that I borrowed from Harry:
Fish were left in the tank since they were hiding under rocks.
Then I started moving live rocks. I thought some of the rocks are too big for me to move it, but as they say, when there is a will, there is a way...
I stirred up the water in 120 so much by moving the rocks, I could not see anything, fish or remaining rocks. After moving all the rocks to the new tank, I realized that I did not have enough water to fill it up to the top despite the fact that I had the new tank filled to the 2/3 of the way. Although I kicked up some Southdown a bit during the move, the tank looked still clear enough. I wondered if I should wait and make more water or go ahead and fill the tank with the really cloudy water from 120. Well, I decided that I should not wait. In the hind sight, I should have drained some water from the new tank and aquascaped the rocks, but I was a bit in a hurry to move everything into the new tank. So this is what happened next:
I could not see anything but at least the tank was filled all the way. I considered waiting on moving the corals until water cleared, but I figured that the tank had a far better condition than the container that they were in did. So in they went.
A couple of hours later:
You can vaguely see corals laying around the bottom of the tank.
I could not see my huge Rose milli right underneath the surface of the water:
