Need help IDing coral

[scubarich]

This encrusting coral is taking over my tank...and I don't even know what it is. The polyps are tiny and it has a skeleton. It just showed up as a speck and starts expanding over the rock.

Thanks in advance for input.

I have a bad feeling it will eventually cause me to have to completely redo my entire tank. :-/
