Been getting in a bunch of new coals this past week and have been using this product from Brightwell Aquatics called Restor. Corals have seemed to like it and all of them healthy as a horse by evening time shortly after adding to the tank & acclimation. I target feed thirty some odd corals in my 15 gallon reef. 2mls of Red Sea AB+, 1ml of Restor, 1.5ml Phytogold Medium, 1.5ml Phytogold Small and a 1/4 tsp of Reef Roids. I dilute with 24ml of tank water. These corals eat better than I do! LOL Got a 60ml bottle of Brightwell Aquatics Coral Aminos on the way to try out too. Probably at least rotate AB+ and Coral Aminos every other day if not switch completely.
