Are you any good with DIY stuff involving PVC
? There are some great things you can do with building frames for the LR
that allow for huge pillars, shelves, caves, etc. If nothing else, it can help support the rocks so you can pile them higher. Currently, my aquascaping is like a W. Tallest points are near the left and right ends of the ****, then it dips down, and there is a smaller rise in the center. The right side has some great caves and hidey holes. Left side looks like a mountain peak because of a fantastic huge piece of base rock I found.
