Not sure I know what U mean by cycling your QT. I use the water right from the main. If your useing frozen cube's, make sure you strain it after it thaw's with RO/DI water a couple of times, drain, put in shot glass, I put 4 drop's per cube of KENTS GARLIC XTREME and little tank water, If your ordering your fish on line, get a bottle of KENTS. Do the same with the Nori strips, put it on the clip, dip it in the tank water for a few seconds to get it wet ( Watch out they dont take the nori right out of your hand like mine do ) put it on a plate, put a few drops on it , let soak in and your on your way. This is what I do, not saying it's FULLPROOF, but it has worked for me, GOOD LUCK! :beachbum:
