I use to have a 20 and a 29 gallon aqaurium but do to an emergency I had to leave my house and everything in the 20 gallon died. I now want to move the live rock to the 29 gallon. I have about 15 pounds of rock. THe question is how should I prepare the rock to put in my 29 gallon. THe 20 gallon had an aneome, brain coral, 1 fish and a kenya treee. Could the dead aneome cause the rocks to be contaminated? Also should I add the rock 1 piece at a time and should I scrub them or just rinse the rocks. Any information would be appreciated, thanks.
