Have a 10 gallon saltwater aquarium and just wanted to know if I can add live rock to a fully cycled tank that already has fish and invertebrates? I have about 7 or 8 pounds of live rock and wanted to add about 4 more pounds. Tank is fully cycled and established. Will this case an ammonia or nitrate spike?
