My LFS is having a 40% off sale this weekend and I had just set up my tank w/ saltwater and sand but no rock. If I put in 40lbs (46 gallon bowfront) of rock, will the ammonia spike kill most of the rock? My friend has a wet/dry on his reef and I was wondering if I took some of his biomedia and put it in my sump if that would stop a large portion of the spike?
