Combination of things. One major stress was the temperature -- it was like 104 degrees after the storms, and the corals have a pretty narrow thermal range. Fish didn't like it either. Probably the next biggest stress was no water movement, meaning low oxygen. More of a problem for the fish, but corals do rely on water movement so that sediments don't settle on them and irritate them. No light -- corals depend on light for their nutrition. So everything combined was just too much.

One reason I was able to get away with no filtration is because I kept small tanks, less than 50 gallons. My filtration was totally biological -- lots of "live rock" and sand. The filter I currently run on my planted tank is just some sponges and the little ceramic rings -- yeah, I'm catching more of the fine debris and cleaning it out monthly, but really what you're doing is creating more surface area for bacteria -- biological filtration. You could achieve the same thing by creating more area in your tank to perform the same function.
