Hello all i have a 125g tank i am going to do into a salt tank i was wondering since i live on the coast if i can use live rock from the ocean for my fish tank? And if i can do i have to cure it??? and how do you cure live rock ?? And would it be ok to get a few live rock and mix it in with some base rock? for my filtration i was thinking of using a good skimmer and power head .. what else would i need to get beside a good heater and lighting ??? any input will greatly be appreciated
