OK, mine don't float. Am I missing something?
"This Hawaiian dry-base rock is ideal for all marine aquariums.It comes from a quarry in Hawaii and is used in the paving of the runways and roads.Instead of importing asphalt, they crush this up which is why a lot of roads there are lighter in color.The rock is a calcium-carbonate base,which makes it very dense and helps stabilize the ph
to an average of 7.8-8.2.This makes it great for african cichlids and all marine environments.
There are plenty of holes,fissures,and cevasses for smaller marine inhabitants to find shelter.Live corals,corallines,macro-algae and the many varied species of anemone all adapt quite easily and begin to show developement quickly.
The color varies from a nice light cream to a red-bronze hue which can brighten up an aquarium in contrast to the dark volcanic and lava base rock currently in local stores.It's dense characteristics and hard structure keep it intact unlike the soft Tufa stone.If you look you might find fragments of shells and calcium tubes whos owners existed long ago.
If you used all Live rock it would cost alot and the pieces you put on the bottom are going to lose most of their life in darkness,using our rock as 80 percent of the total rock in your tank and adding just a few Live Fiji,Tonga, or Marshall will allow an ecosystem to develope and Save You Money.

I was mistaken, not volcanic rock after all.
