Upgrade to New Tank

Any advice or suggestions would be great.



This is what i have.

60 gallon -4ft tank

T5 4 bulb light structure

HOB Skimmer (Bak Pak2)

3- Hydor Power heads.

Uv Steralizer



10 Fish

12 corals

1 anemone

110 lbs of rock

60 lbs of sand





I will be moving to a 90 gallon w/ 30 gallon sump.



Also 4 ft so lighting will come across.



I have 35 gallons of RO DI water on stand by for this process or before i start the move.



I was thinking of getting 2 large totes. Throwing heaters in them. This way I can move my current water into them with fish in 1 and corals in another. I will then use my 5 gallon buckets to store my rock/sand.



sand is only 6 months old so it should be good. I may wash off the rocks before putting back in or does that lose good bacteria?



Any other Suggestions?
