Spectacular pics and corals. Wow, you have a lot of water with all those systems going. Do you have any moisture problems where these systems are? Are you acheiving this with what I would consider "old school"(water changes and excellent husbandry) or are you employing techniques, like dosing additives like Amino Acids,Potassium, Vodka, sugar, etc.? Whatever you are doing seems to work great for you. Keep up the awesome job. Have a good day.
