I heard this sound like wires touching and smell burning plastic. I look in the back of the tank and the heater cracked. I probably hit it on something yesterday. I picked the glass and heating elements out and somehow my fish are still alive. I did an immediate water change out of 20% but my feather dusters, snails and hermits don't look so well. Is there some chemical in those heaters? All testable water parms are fine. My skimmer was going crazy too and I wonder if that had something to do with the broken heater. Also I can smell something burnt in the back where the heater was.
