CC=crushed coral
PH=Power Head
LRS=Local Reef Store/Shop
"Ma and Pa" stores=Family-run pet stores in which the people usually know what they're doing and are thus a good place to buy pet items.

CC=crushed coral
PH=Power Head
LRS=Local Reef Store/Shop
"Ma and Pa" stores=Chain stores like petco & petsmart that u should never think about buying from unless its for a good reason.

Actually I think you have that last one wrong. "Ma and Pa" stores, everytime I've heard it, is in reference to a small, family owned type store, which if the people know what they are doing, is usually the best place to get fish from.
