Yeh I don't understand why some people have such a problem with a tank cycling. When I started my 75 I started out with approx 30 lbs of LR and 60 lbs of LS. I never saw an ammonia,nitrate or nitrite spike. Levels remained very low. But I have read on this forum and on RC about people who have huge spikes that last quite some time. And then like you said Bryan you can see people who have another cycle after the tank should be established. I'm sure a lot of it has to do with basic husbandry. Trying not to grossly overfeed, keeping water parameters in check, not adding a bunch of fish at once, making slow adjustments, etc. I see people struggling with there tanks and it makes feel lucky and thankful my reef experience has gone as well as it has ( quickly knocks on wood!!). And now I know that a QT will not start cycling within a week if you use established water from the main system. I hope I will not have to use one again but something tells me that I will at some point in the future.
