If you haven’t heard of David’s aquarium then where have you been? His aquarium is one of the greatest private aquariums in the world and he recently made changes to this wonder. The video is taken 4 months after he made a move to more hard corals and smaller fish in which he completely rebuilt the inside of the aquarium. Plus, he gets to use all the latest Deltec reef equipment and he might even been using one of their new protein skimmers. In case you were thinking it isn’t as impressive before, you will be sadly mistaken as it is definitely worth about 10mins of your time to watch this amazing video & tank.
