Crushed corals for a FOWLR tank

[EmilyB]

I used cc when I first started both the reef and the FOWLR.

The only thing with crushed coral is it traps so much detritus, that you really have to vacuum it when doing water changes. Mine still had a lot of life in it, worms , pods, etc. back where I couldn't vacuum.......

And as far as it being used...my personal thought is that wouldn't be a problem.

Guess a lot depends on the type of fish as well....some FO specimens need a softer substrate...etc.
