Hello to All! This thread is an extension of my current tank upgrade project but I wanted to list it under the Reef Cleaners forum area since I have become an official member of the Reef Cleaners rock fan club! I recently ordered a bunch of rock from John and in true form he was extremely accommodating in meeting my request for certain sizes and shapes of rock. This was my first rock order ever and the upon initial inspection when it arrived, (much to the great curiosity of my co-workers...."you ordered ROCK online?".....) the rock went way beyond my expectations. Wanting to do something a little different with my rock scape in the new 50g I am working on, I took the rock to a local stone and granite supplier who cut it for me on a commercial wet saw. When I shared the initial pics with John, he referred to it as deli sliced rock and the name has stuck with me The attached pics are proof positive that Reef Cleaners rock not only looks awesome on the outside but on the INSIDE too!
