i added 25 lbs of deep water tonga to compliment 30 lbs of premium fiji in my gallon. Very cool shapes and colors (oranges and pink algaes). But I guess my light was too strong for this algae because it all died off and was replace with the usual purple coraline algae that dominates most reef tanks. I would buy rock for it's ablity to hold colonies of bacteria. To do this, you should have porous rock. florida rock lacks these qualities compared to pacific rock so more of it needed to do the same job.
It boils down to preference.
