Aquarium Calcium & Aquarium Kalkwasser Additives


The two most important elements to supplement in your reef aquarium are calcium and alkalinity. If your reef aquarium is doing well, then you will need to supplement calcium and alkalinity. At MarineAndReef.com we have dozens of calcium & kalkwasser additives from Seachem, Brightwell Aquatics (Calcion / Reef Code), Two Little Fishies C-Balance, & Sea-Lab; some of these additives are two-part supplements for both alkalinity and calcium.
