I have been using their coral supplement program since it came out. Reef foundation A,B and C - Reef Colors A, B, C and D - Reef Energy A and B.
Foundation A, B and C are dosed daily by a Bubble Magus dosing pump. Reef Colors are dosed by hand twice a week. Reef Energy A and B are dosed by hand once a week.
I have been very happy with their entire line. I mix the Calcium and Alk from the powders.
Tank is a 65 Max tank. SPS started all as frags. This is the tank as it sits today. I strongly recommend giving them a shot.
