granite?

  • We are currently upgrading MFK. thanks! -neo
I've seen some ponds that used granites in replacement of tiles
 
I use granite in my frontosa tank with no problems at all. I get the scraps from making grave stones. They make great natural looking caves when the chunks are on sand.
 
I use them as natural caves. Good thing is that you can cut off what you dont need by hitting it with a hammer to break some rock off.
