I just setup my 10 gal, saltwater tank (mixed the water last week and then set the tank up yesterday). Today I rechecked the salinity and it is right on 1.022 (same place it was 24 hours ago) and added a2-1/2 lbs pieceof live rock (starting small.......$$$ isn't free flowing).

I'm itching to add some small snails, hermit crabs, etc. (janitors). Do Ineed to wait for any reasonor can I just add slowly (like I would in freshwater) and just keep watch?

To keep the live rock "alive,"I just put a little food in right?
