Reef Chemistry Question of the Day [HASHTAG]#157[/HASHTAG]
Limewater (aka kalkwasser) that is saturated (that is, it has dissolved all of the calcium hydroxide into fresh water that it can) at 25 deg C contains about 41 meq/L (114 dKH) of alkalinity and 808 ppm calcium.
That calcium level isn't even twice the level in seawater, but the alkalinity is more than 16 times as high as seawater (420 ppm calcium and about 7 dKH alkalinity).
So how can it be a suitable way to add both calcium and alkalinity to a reef aquarium without creating an imbalance?
Good luck!
