I spent the past few days, a few hours on each... attempting to re-arrange my rock, to get a more suitable rock layout before I add anything else to the tank, as far as fish and corals go. The look I have now is 50/50 the way I want it. I like the way I was working to, except it doesn't quite suite what i want. The problem is that most of my rocks are large and bulky, difficult to stack. I have a couple smal pieces of neatly shaped ones, but they don't do much when the other pieces don't work out well. The idea I was trying to work on was to place a rock pile on each side of the tank, to make a mountain slope or some sort, sloping towards the center of the tank. This was impossible to create do to rock sizes and shape. My rocks were to big and bulky so stack up towards the air and to create a slope. I attempted to make the slope on one side of the tank, which worked a little better, but not quite ready. I plan on buying some lava reef rock to help build with it, plus its really porous. Anybody have tips or ideas they could suggest to me? I experiment a lot, but usually it doesn't lead anywhere.
