Rather than leaving a 1/4 " of crushed coral and covering it, it would be better to do a section at a time. That way you are less likely to start a new cycle. If you do it this way, the old crushed coral will help seed your new sand. If you cover the crushed coral you will kill anything benifitial on it. You will also find that the crushed coral will work its way to the surface of the sand over time. I find that most bagged live sand is fairly clean and doesn't cloud the water to much if added carefully. I use a cylander like a gravel vac, fill it with sand and lower it into the water with my hand over the bottom and then let it slowly slide out the tube. good luck!

I should have mentioned this before, but I plan on leaving about 40% of the current substrate in the tank. All of the substrate under and close to the live rock will remain. My rock is all piled up in the back-center of my tank, so I would be replacing the entire amount of substrate in the front of the tank and the sides. By doing it this way, am I able to take out larger portions at a time each week?

If you leave the cc in, the finer sand will likely just settle through the cc.

To put the sand in your tank, I use a piece of 4" pvc pipe a little longer than the depth of your tank so the end is just above the water. By placing one end on the bottom glass and the other out of the water, you can then use a measuring cup to dump sand into the pipe and let it settle to the bottom without clouding your water.
