Ok so my friend from work is big into salt water I have done lots of fresh water but this will be my first salt tank he's giving me a 10gal and some live rock all I'm doing is getting live sand, a heater and giving him a filter pad so I can steal some bacteria first off how long should I wait before I get the pad back? And any tips would be nice btw I want to do a small reef tank with a clown fish or two and a bottom feeder
