I have been searching online and watching you tube videos on both styles. Is a shallow tank easier and better to handle because of its shallow water access to bottom of tank. What are new reefers running these days ?? Also all in one tanks seem like they are popular is the innovative nano marine tank most desired ?? Was looking at their80 gallon version. I am very new to salt water hobby so I would like your feedback to steer mein te right direction. This set up will be going in my office where I have been running a 29 gallon biocube now.
