So i was told when cycling to just cycle in the main display, no skimmer, no circulating through the sump and no lights. Can i circulate through the sump, theres approx. 30 lbs of live rock in the sump. If i do just the display, will the system go into another cycle once the sump is online? I plan on useing a couple of raw shrimp. Leave it in the tank for 3 days then start testing for Amm. Any suggestions would be helpful thanks C
