While this 90 was boiling to perfection I had a 55 gallon going with about 50+ pounds of liverock in it, that live rock was all purchased at my LFS for 5.99 per pound, and it was basically wet rock when purchased. I made it grow with coralline algae. After plenty of research I decided to spend the money on baserock and make it live myself, saved a ton of money. It can take months to get the coralline growing on it. You should purchase some live rock to get the pods and worms that may be in them to help seed the base rock, but you don't have to spend a fortune on it.
Get it :jumping:
Here is another early tank shot after transfering the liverock over from my 55 gallon. Since this shot I have added much more baserock and have been building it up.
