Hey all. Still in the building process of my new 300 gallon deep dimension reef aquarium. It features a full Ecotech Marine package of 3 gen 4 XR30 pro LED's, 3 mp40 wavemakers and an M1 return pump. Also for a skimmer a Reef Octopus 260ss. Stand base is built with 2 x 6's and 1/2" plywood in the sump area and a 3/4" plywood on top . Going with mostly Caribsea Liferock and some pukani. Currently at the stage of building my sump, a 120 gallon tank. 4' x2' x 2'. Sump will include a refugium but also debating growing mangroves in my system and how to do it.
