I have been in the saltwater arena over 20 years in and out. I have noticed lots of technology changes. I just wanted to hear what is the gold standard for equipment on SPS systems? I have LED lights, a Life Reef Skimmer, Biopellet Reactor, Refugium. Are the latter 2 really required? Are people doing fine without them? I do notice a good pod collection in my refugium which is made by Life Reef. It is a totally separate system from the sump so I am able to control the flow of water through it. Let me know your thoughts.
