Well, I am going to have a HUGE fuge (rhymes...lol) so basically I would only be able to have about a 1 inch sand bed because I would be using miracle mud in the fuge. So really, the sand would just be for decoration in that tank, and it would just trap stuff (not really, I would have sand stirrers) but it would be a full SPS tank, so IDK. I am still debating.
