There is water, rock and stuff in there now, and there has been for about 3 weeks now...
The Caulerpa Prolifera in the sump...
The Whole Unit...
The Display Tank
Had a small hitch as a return pump fell out of it's mounting and caused water to stop going between the tank and sump overnight. Nothing major and all water remained in the system. I have had to change my plumbing to something more permenant to prevent it from happening again however
