Something interesting happened to my mom's tank. We set up a new 90g for her this weekend, and on my way home in a blizzard she called FRANTIC. Her heater BLEW UP in her tank. She said it looked like a lightning storm and sounded like a shot gun in her living room. She lost a Kole Tang, Blue tang, Sebae Anemone, Short Spined urchin, Tuxedo Urchin, Pep shrimp, cleaner shrimp, all of her coral and snails look to be checking out too. It was a Marineland heater - the new plastic one. She called Marineland and complained, they are sending a new one, and they need an estimate of livestock lost so they can replace it. Just a solemn reminder of what CAN happen in this hobby. Sucks, we worked so hard to get that tank where it was at. She had all kinds of leathers in it.
