I setup a new 39 gallon tank Saturday morning and am new to salt water. I let the tank sit overnight to stabalize the temp and let everything settle. The tank was at 77 degrees, the PH was just over 8.0, the SG was 1.021 and there was no ammonia, nitrites or nitrates. I went Sunday and bought some live rock from the local fish store. I wasn't exactly sure what to do with it to start so I asked the person at the store and he said since it was a fresh tank with nothing in it I would be ok putting the rock directly into the tank. So I took it home and put it in the tank and arranged it however I wanted it. By Sunday night I noticed there was some white patches appearing on the rock. I read up some to see if I could find out what it is and figured after reading some it was some die off from moving it to a new tank. So I left it over night and all today and came home from work and noticed there is quite a bit more white on them now. I was wondering if this is normal or if I should do something to the rock to help fix it? Pictures are at the following link.
