Everyone is different. Tap water, no acclimation, using a biocube ;), buying from petco, not dipping, not wearing a seatbelt, not flossing twice a day- some people half ass life and it works out for them, others do these things and it has unpleasant results. Guess it depends how seriously you take stuff and/or how much of a gambler you are. There's always luck involved as well. I think we all know what we SHOULD do, and, at the end of day you're playing russian roulette when you just cross your fingers, plop the coral in and pass out without brushing those pearly whites.
