live rocks changing

[dhuv]

I have been seeing that there is lots of power like material around my live rocks. Recently I noticed that my rocks have more holes in them than I remember. It seems that the holes are getting bigger and the power material is what used to be the rock. Is this a normal process as my tank matures? My tank is 1 year old.

54 gallon bow corner tank
~50lbs of live rock
sump, with 1 venturian style skimmer and 1 pump.

Thanks in advance for the help.

Some erosion is normal, but I wonder if you have some type of animal boring through your rock. Is it occuring on all your rocks, or just a portion of it? Any chance of pics?

If I had to guess, I would say it could be an urchin. Have heard that they could do that, but without pics, ya never know.
