Our second tank crash and the horrors of uncured live rock

The second crash we went through after we started keeping saltwater fish was a huge one.

The first signs that something was wrong in our tank was that the water started to smell really bad. Normally there is hardly any smell from a saltwater tank, so that was a bit odd. A few days later I noticed that our Flame Angelfish started to lose his vibrant red color. The next day it was at the bottom of the tank dead and had even less color. At this point I was pretty much lost as to what happened.

A few days later the same thing happened to our Spotted Mandarin and it suffered the same fate. I could not figure out what was going on. I read everywhere and couldn't figure out what was happening. In no time our Red Head Solon Fairy Wrasse passed away as well. I was just so lost at this point.

Soon after our Black Ocellaris Clownfish start acting weird and swimming at the bottom of the tank. That morning I went to a trusted LFS and asked the owner what his thoughts where. He blammed the live sand we used and also that we were using treated tap water. That day I took the remaining fish (Ocellaris Clownfish, Black Ocellaris Clownfish and Skeletor Moray Eel) and inverts out of the tank. I tore the tank down and removed all of the water, live rock and live sand. I added in crushed coral and RO water, with half of the water being from an established tank. I also added in some liquid bacteria.

While I had the rock out of the tank, I noticed that two pieces smelled terrible. These were the two newest pieces I had just bought recently. It looks like the rock had not been cured and the LFS did not tell me this when I purchased it. I threw the bad rock away and added the remaining livestock in.

That night the Black Ocellaris Clownfish died and I felt terrible for our Occellaris Clownfish who had paired with it. The Eel and other Clownfish pulled through and are still doing good to this day. This crash taught me the hard way about uncured live rock and what it can do to your fish.

The next crash I had was a few months away, and it was from no real fault of mine, minus not quarantining fish. I was put in a very bad position and the result was some fish deaths... more on that later...
