Well not the worst but along the same line. One of my 2 30 gal refugium glass cracked about a week ago. I lost about 30 gallons worth of my 29 gal setup. I had the display and 2 30 gal glass refugiums to increase the total amount of water circulating through my tank. Good thing I have redundancies built into my setups and didn't suffer major loses other than a little higher than normal ammonia levels do to the high bio load in the tank and lowered amount of water volume.
