Here at SaltySupply.com we offer some of the best Aquarium Additives for you marine and freshwater aquarium. Many of these additives are important for the well being of you aquarium inhabitants. Some of the basics for reef tanks include Calcium and Alkalinity, magnesium and Iodine. While many aquarist's use many different additives in their aquarium there are a few basics that we suggest every aquarium hobbyist use. First being Calcium, Alkalinity and Magnesium, these are essential for calcium based corals and coralline algae to grow in the aquarium.
Additives are a very important addition to any aquarium as many trace elements are depleted as corals absorb them. These need to be replaced on a regular basis by water changes and regular addition of calcium, alkalinity, magnesium and other trace elements. Brightwell Aquatics carries a full line of products with everything you will need to keep your aquarium parameters in the ideal range. We recommend 8-10DKH Alkalinity, 400-420ppm calcium and 1300-1480 magnesium.
