I have over 500 Lbs. live rocks (mostly Tonga & Soloman Island) in the 270 gallon sump of my home tanks at Great Neck. They have been there for 10 years in average, some are as old as 20 years.
I am thinking to sell some of them to make space for refugium, I am asking $5.- a pound with a minimum of 100 Lbs.
