Rubble rock

[saturn13]

Hi everyone,

Just got back from a trip to the carolinas. Picked up a lot of shells and dead coral pieces, i've used these a lot in past tanks in the sump and for frags, but was wondering what the community's thought might be on this - positve or negative?

Properly cleaned they are probably okay. Not sure I would put in my tank personally. Also not sure about the local regulations on SC.
