Baking soda (sodium bicarbonate) plays an important role in the ph buffer system. It is also falls under the category of alkalinity. ...

In a closed system aquarium with a heavy load of hard corals, it is hard to maintain a necessary level of calcium for proper exoskelton growth of hard corals. Water changes only replenish a small amount of calcium and then the remaining is either added vi ...

Kalkwasser has many benefits other than adding calcium, it maintains ph and alkalinity, precipitates phosphates, and also improves protein skimming of organics. ...

Just like calcium and alkalinity, magnesium is also depleted rapidly in an enclosed aquarium system. It aids in the uptake of calcium inorder for hard corals to form an elaborate exoskeleton. ...
