Reef Chemistry Question of the Day #244
One of the primary reasons that reefers may needed to dose an unbalanced ratio of calcium to alkalinity in a reef aquarium is to counter the effects of a water change that does not match the aquarium.
Suppose that your target levels in your reef aquarium for calcium and alkalinity are 430 ppm and 8 dKH.
Which of the follow salt mix parameters, when used for water changes, will cause a substantial imbalance in the above tank such that more alkalinity than calcium is needed when dosing?
A. 5.9 dKH, 416 ppm calcium
B. 6.6 dKH, 421 ppm calcium
C. 10.8 dKH, 449 ppm calcium
D. 12.2 dKH, 492 ppm calcium
E. All of the above
Good luck!
