welcome asonitez.
how did you pick up that rock? in buckets and left it dry for the ride home? covered it with wet newspaper? submerged in buckets of water?
you will see a cycle. you'll go through different algae blooms, and depending on how you transported that rock, ammonia, nitrite, and nitrate spikes as well.
do you have a test kit? you'll need to start testing your water to see at what point you are, and also, it's a good practice to test your water periodically if you have any livestock in the tank.
i hate to put an end to your alleged "lucky streak", but i think you are going to need to replace that skimmer with a good one.
also, remove the bio balls from the wet/dry. they will work against the live rock.
basically the cycle is the same as you've experienced with freshwater.
you might start thinking about lighting. what corals will you be keeping in this tank? there is an on-going lighting thread in this forum you should read before purchasing. also the topics marked *sticky* are very important reads.
again, welcome and good luck with the tank. and try not to add any more livestock until you are sure that the tank has cycled. :wink:
