I have a 12" shallow tank with 3000 gobs of flow total; 4powerheads and a return pump. I only added the final 1050 koralia unit last week after diving my sand a month to gum up and my sump is now full of sand. Probably because my tank is shallow, but you can see the nitrogen pockets already developing. I have about a 2" sandbed. Well that what I started with. Now I have 4" deep areas and some that are 1" or less. Looks more natural but my tank has looked "foggy" for a while.

I got my sugar sand from Eco reefer.

The Carib special grade sea floor will come from exotic reef in east London. It's a new place but u need tO call ahead for they don't have set hrs yet.
