Minor Tank Disaster: Heater Blew Up

[spedly]

Thanks for the replies. This might be a non-issue. The tank is looking a lot better today. A lot of the black stuff that was on the rocks is gone. I'll wipe down the inside later and post a picture of the black stuff on the glass.

I guess the only thing I need to worry about is my CUC. They've disappeared. I suspect the hermit crabs buried themselves in the substrate. I hope I don't get a mass die-off of inverts.
