So in June I moved a 75G setup as follows:
Mixed a good 30G of fresh saltwater, in large rubbermaid garbage cans
Removed liverock to several 30-50G rubbermaid tubs, small powerhead in each.
Removed fish to their own 5G buckets (1 fish per bucket except for 5 chromis in one)
Drained all water into 30-50G buckets, small powerheads in as many as I could
Removed sandbed into several 5G buckets with about an inch of water.
Loaded everything onto a truck
At new location brought all rock, sand and fish inside first and plugged powerheads back in
set up stand and tank (don't forget to level it!!!)
Added sand
Added about 1/3 of the water, slowly
Added most of the rock, corals left in tubs with powerheads running
Filled rest of tank with cycled water, topped with new (I ended up with 20G of fresh saltwater ... you'll see why).
Plugged in all pumps, etc and off we went.
Fish in last
Corals in the next day
Skimmer turned on only after corals in. Lights turned on 24 hrs after that Sandstorm was halfway settled in 24 hrs, gone after 36 hrs
Skimmer cup was going nuts ... had to empty after 2 hrs, then 4 hrs, then 12 hrs, then every 24 hrs for 3 days. Also, did a 10% water change after 7 days, and another 10% after 7 days. Thus that 30G of fresh saltwater was gone in 2 weeks.
I lost one fish after a month as it never ate. I lost two SPS from Big Tumbles when aquascaping. The rest was all my fault.....
