Hello everyone! After many years of experience with a freshwater aquarium (300 liters), I decided to start a budget (or mid-range) marine aquarium (fish and corals). As a result, I have a lot of questions for which I would really like to get direct answers. As of today, I have ordered an aquarium measuring 110x70x50 (length x width x height) and plan to get a stand similar to the Juwel Rio 400. So far, that's all I have besides the questions: 1. Do I really need a sump for my volume, or is an internal or external skimmer sufficient? 2. What about T5 lighting? How many lamps do I need? Or is there another lighting option (I can't install a fixture on the ceiling - it's drywall)? 3. What circulation pump would you recommend? What else do I need to set up and maintain the aquarium?
