I started seeing levels go up indicating a cycle after about 4-5 days. But I think all situations would be different. Reason my cycle was short was because I just took my 55 gallon sump offline when I swapped tanks. Then when i was done a just activated the sump again which housed.my skimmer, pumps, macro algae and some live rock and about 45 gallons of aged seawater. That's why my cycle was so short. Did you keep your sump active while swapping tanks or did you start fresh with a new sump too?
