I set up a new reef and its a 20gallon. I put in twenty lbs of live sand and 10lbs of live rock. I want to add more rock but my question is should i wait until the tank cycles? or just add more now? and should it be live to get to 20 lbs total or can i use dead rock? Thanks guys
Add more now. You can use live or dead rock, but you want the tank to cycle with all of the rock in it. You want the bacteria colony that grows to cover all the surface area you can.
