Ordered hybrid, reef saver and shelf Marco Coraline rock for my aquascape. I wanted a negative type scape with enough swim lanes and open space. Leaving 4 inches in the front and 3 inches on the side and back to allow enough room for coral growth, and swimming space. It is very tempting to build to high and wanting to use most of the rock. I ended up using less reef saver rock than I thought. Went with 3 individual islands with your typical arch in the middle. I was impressed with the shelf rock pieces, makes for great scaping and lots of coral space when it is angled. The hybrid pieces are really nice, as they can be used as small shelf rock in the scape as well. I ended up using about 60lbs of rock. I will add a couple of island pieces for zoas at some point.
I'm excited to see how it is going to look in the tank with the TBS sand. Next is getting the mixing station built.
