question about replacing sand

Ok i have a 55 and have the crushed coral about 2 inches deep..would it be more beneficial to me to replace it with finer sand and a deeper bed? Also i want to use the silica sand from Home Depot but have heard mixed emotions about it and have read the thread about it on the reef chem. How would i replace the cc w/o draining my tank and removing the LR...or is that impossible?

What kind of corals do you have in your tank?

I did this changeover 1 time just doing about a 1/4 of the crushed coral at a time working from one end to the other replacing it with sand. This did work for me at the time.
