I am no longer an acrylic drilling virgin. I did my first hole tonight and it took about 15 minutes total of measuring and drilling. I choked my drill way down and went very slow. As stated earlier it was easy. Thanks a ton for the advice the return pump that I am planning on using is the RIO 32hf if you all feel that is to big I would gladly buy a smaller pump. I will probably use one of the chambers to grow algae with some live rock and a sand bed for pods.
