So I've been running my tank with a bare bottom recently, but since I'm moving the location of the tank and re-scaping it i figured now was as good as ever to add sand. I've read good things about the Fiji pink? Is that good sand? and if so wheres the cheapest place to get it? Also when I get back from vacation next week and redo my sump with a large refugium, Is there a better option for sand in here? I had read to put finer sand in the fuge since its lower flow. Has anyone had and success with this?
