My 60 gallon has been unattended to since last summer when all of my fish died after I introduced a diseased Royal Gramma. I have about 100 lbs of live rock in there. Now, I a getting back into the hobby and want to redo my tank. Anthony Calfo said that I should keep the live rock, but I should do a 100% water change on my tank. So here's my question: Will the live rock be okay in the newly mixed/made water? Can I plop the rock in as soon as the tank is filled? Please, help.
