Well obviously the best way with no casualties is to set up and cycle the new tank to match existing conditions in your 55g reef tank, then just a simple process of slowly moving your livestock into the new tank over the space of say a month or so to avoid large nutrient spikes. However if you wish to take the quicker riskier way of an instant changeover fill the new aquarium with 55g of new water, mix to match salinity, temp and ph of existing 55g reef tank, do this a couple of days before the transfer. On the day of the transfer, remove live stock from existing tank into holding tank(20 litre bucket ect.), separate live stock if neccessay(anemones), then use all of the water from your old system to fill the new one, this will give your clycling process a good headstart. In addition I highly reccomomend using "Seachem Stability" to help cycle, this stuff is magic, i can almost gurantee that you will have no major ammonia or nitrite spikes when using this product in conjunction with live rock. Once you have filled your new aquarium with old water, slowly acclimate the live stock to the new tank and top off with water as needed. On a sidenote, I do not reccommend having more than one anemone species in a closed system such as yours, the likelyhood of "chemical warfare" is a danger not only to the anemones health, but to all tank inhabitants. What sort of anemones do you have? Hope this info helps.
