I think that's a little unfair. Okay, if a person has a tank for nine days and goes to the aquarium and buys a huge colony of SPS, a flame scallop, a green mandarin, a Copperband butterfly and a leopard wrasse, then yes. That livestock is doomed.
But if a person starts a tank with cured LR and nine days later their levels are all zeros and they go to the store and buy a toadstool leather, some zoanthids, a few chromis and maybe a tank-bred false perc, do I think that LS is doomed? No. I think he might be stocking too quickly, but there's no reason that group of animals couldn't survive in a tank that just finished cycling.
I might get flamed for this, but I started stocking my tank within a week of putting water in it. Granted, my rock had been curing for over a month elsewhere, but I know a lot of people would say this was way too soon. Yet, most of my LS is still alive. I've lost one coral, due to a sponge suffocating it while I was on vacation, and I've lost a couple of fish to disease/poor quarantine procedures. I've had almost no problems from poor water quality. (I've been having some NOW, but it's because I've been overfeeding in an effort to get my mandarin on frozen foods.)
