DSB or CC Substrate?

[Bryan]

Don't know if this will help you but in my situation I was setting up a new 125 gallon. I decided against using a DSB in the tank. Instead I used a DSB sand in my 33 gallon refugium and used a 3/4" layer of fine crushed coral in the main tank. So far everything is working well.

I like the look of the fine crushed coral better, plus I get the benefit of a DSB hidden away in my refugium.
