I am upgrading from a 60 gallon cube to a 100 gallon tank and I am using the same 40 gallon sump + separate refugium (which has a 4 inch sand bed) plus 70 lbs of live rock which I've migrated from my prior 75 gallon tank to the new 100g. I've had the live rock in my tanks for ~6 years. My question is should I plan for the same cycle time as a new tank even though I'm migrating everything except the sand from the display tank? I'll be putting new live sand in the new tank with some of the sand from my DSB from the refugium. I also run an AquaC pro skimmer, phosban reactor, and charcoal reactor.
Thanks for any advice.
