ROCK OF THE WEEK #6 - THIS EDDIE ORIGINAL ARCH SCULPTURE
WILL MAKE A WONDERFUL STEADY BASE FOR YOUR REEF

Rock of the week 07/21/03

Eddie has done it again. He has created a rock masterpiece. Using aragocrete, and GARF's simple method (which you yourself can try; instructions are on our website), our rock sculptor has made something both beautiful and useful.

.I noticed this sculpture first because of its pleasing shape. It is covered with interesting curves and peppered with holes. The front part of the rock is curved slightly, and in the center is a large opening which leads into the middle of the hollow rock. To my human eye, this shape suggests secret undersea caverns, the kind in which pirate treasure is hidden and mermaids frolic.

While this rock would work well from an aesthetic standpoint, it also is biologically perfect. Often times I am asked about biodiversity in a tank. Biodiversity creates stability and well, having a variety of organisms just makes a tank more interesting to watch.

The way to create biodiversity is to have a variety of habitats. A reef tank, by definition, has highlight. But what about the organisms that don't like light? Caves such as this, provide excellent habitat for animals which would prefer not to deal with the bright illumination of your lights.

Here at GARF, we have many caves that have become sanctuaries for colorful sponges, carnivorous gorgonians, species of cup coral, and wineglass hydroids, all of which will not grow in bright light, as they will become overgrown by photosynthetic organisms.

The caves design also makes it perfect for those secretive creatures: it has a total of 27 holes all around it. These holes will ensure that the water inside the cave is flowing, and has plenty of room to circulate and mixwith the water in the rest of the tank.

This design will prevent stagnation and allow animals inside the cave to get the full benefit of any food material that is given to the bigger tank. An aragocrete cave is definitely a good addition to the biodiverse reef tank.

This cave is 19 inches long, 8.5 inches high and six inches wide at its widest point. The rock weighs 22 pounds. Like all of Eddie's aragocrete sculptures, it costs five dollars a pound with shipping free, so this cave would cost a total of 110 dollars

Call now to order a cave (we have several different sizes besides this one) for your tank, or view our online instructions for making your own aragocrete rock.
