Just wonder if any body would share stories of times when they lost alots of fish or anytimes where everything went wrong with there tank. My story is when I was cycling my Sw the first time and i woke up to see my Heater crack in half and all the checmials leaked everywhere in the tank. I had to then take all the water out replace all the filter pads and hoses. It all smelled like sufur for a week. All together a 200 dollar set back but i bet thats nothing for other people.*crazysmil
