Lava rocks or Feather rocks
I am in need of a light weight rock that I can use around a fountain. Does anyone know where to purchase the above kind of rocks or something similar that is not as dense and regular rocks? I am in the Roswell area and went to Pikes on Alpharetta Hwy and they did not have anything but the usual. Thanks for any info you can help me with. I am in need of 4 10 gal buckets full.
