Review on 🐠 Seachem Reef Fusion 2 - 1L by Wendy Mellgren

Da Fusion 2 in conjunction with Fusion! is used, I have repeated my comments on Fusion 1 here. Pumps. Their formula is ideal for dosing in equal amounts on a 1:1 basis, but this may vary depending on the needs of your aquarium. Mine requires about twice the alkalinity of Fusion 2 as Fusion 1 Calcium to keep it in the range I like (calcium 420ppm and alkalinity 8.6 dKH). The individual dosing in two parts with dosing pumps gives me precise control over every parameter.
