Should I replace my crushed coral?

[TheRick]

I have a 6 week old 75 gal sw tank. My LFS helped me decide how to set it up and I have about 2" of crushed coral substrate. I also have 50# of live rock with 50 more on the way which I bought online and am going to cure in our guest bathroom(god I hope it doesnt stink too bad, my wife will be mad)

The more I read about substrate the more I am becoming concerned with the crushed coral. Should I slowly remove it day by day and replace it with sand or can I put sand over top of the coral? Or am I freaking out over nothing?

Thanks for your help!

if you get some live sand, the crushed coral with eventualy be seed with the good stuff, oh i hope you are not putting the LR ontop of the substrate, catastrofic events may happen( you rock setup could shift causing something damaged or crushed)

is putting live rock on top of sand really that bad

no it is not. I have always done it and I always check before hand if it is stable. But If you do have fish that dig it can be a good idea, you can always just slightly twist the rocks so that they come to the bottom.

I think that you should put sand on top of the crushed coral if it dosn't become to much substrate to look good. Just a litte bit to cover it up, sand looks way better than crushed coral. Don't get live sand becuase the live rock will seed it in no-time.

Thanks for the all the help. I also twisted the LR in the coral pretty deep and its really stable.

Cool, I am going pick up some sand tommorow. Just gotta find a close place to buy some from.

Well bought some sand from the lfs and he actually had a tank with cc and sand. It didnt look all that great, the brown coral just comes back to the surface. So I just remove all of the crushed coral(pain in ...) and adding the sand in. Water is a little cloudy but the fish dont seem to mind all that much(I scooped the cc out with a mini net over 6 hours and it created a lot particules)

Yup dont bother just putting sand over the top just take all the crushed coral out, as the coral will sift itsway to the stop of the sand.
