100% I would cycle your rock from the LFS.. from other peoples tanks its not so bad since they are generaly already cycled.
Have to remember the stuff at the LFS was shipped in boxes, with no light no heat basicly, could be sitting on the runway for who knows how long.. by the time its in the LFS hands things are dieing left and right.. so, ya.. you need to cycle those rocks.
