Aquarium is 41" x 24" x 24". I will be purchasing from Marco Rock and would like some help with what I will need form them. What sizes, shape, weight with key largo, prime cuts, etc. To give me plenty of styles to choose from for my aquascape? Do I need rods or can I just glue them together? What type of adhesive do I need? Will there adhesive be good? Was also looking at ordering there sand as well to make one order and done. Is there sand good? Which sand of there's to use? Would like suggestions from people who have used there products and how they used them. Also here is my build thread if interested.
