CC or Argonite?

[Cap'n]

Most will agree that you should get rid of the crushed coral.

Suggestions of what you do after that will vary incredibly with everyone you ask. There is a wealth of information and debate posted on the substrate subject on this and many other saltwater aquarium forums.

Do a search and read what others have already said about it. Might be the best way to decide.



I switched to sand a few years ago. Straining all the CC out of the sand was a pain, but well worth it ,IMO.
