Most of the issues with sand come down to a few things...Silica content and buffering capacity...

Although many people have used southdown sand for an aquarium, i would still prefer to use proper aragonite reef grade sand, which is designed for the marine tank purpose..

Southdown just won't buffer you levels, other than that it is fine.
 
nope the CC will come to the surface over time, then things are really hard to clean!!
 
Thank, BTW do you think it's worth changing out the CC to sand? keep in mind I'm moving in 6 months or so and I'm going for a 125 when I do move, I'm not crazy about this Nano thing so the 20l will become a fuge or small frag tank...
 
Yep what he said
