Ok so update time :: pictures to follow when it starts to get good. The main steel piling and digging for filter room extentions on big project is under way. I saw them really digging today big. Concrete underpin to follow. I'll take pics for construction nuts. To me is boring stuff. Bring me back when framed and sheet rock. Few things to report in the current 1500 gallon system though. Since tahiti I have been feeding coral polyps 2x per day and few times per week at night. We using reefroids, reef chilli, coral frenzy, oyster feast, and started making our own pappete with fresh seafood. During this time we got an industrial ro di unit going to be used on new system. The net result is we can make 2 gallons per minute and filling up our vats in just few hours. So.. we also are changing like 40 to 50 gallons per day in addition to the weekly 200 gallon water change. I'd say we doubled our water changes. 400 gallons per week. I can report not a single sps loss from carbon change or gfo change or anything. Not one loss. All polyp extention significantly better. Not even close. Just don't bake your corals!!
