oh, and almost all the rock in the tank will be arago-crete, I will only put a little bit of uncured liverock in to seed the tank, and a rubble in the refugium w/ the cheato.

The reason I am not going w/ a HIATT on this is because I believe that a tank that is to lightly stocked is actualyl incapable of sustaining the hiatt, and of course, the hiatt would have to be outside the tank, and I want my filter inside it... nothing outside the footprint of the hex!
