I recommend 7-11 dKH, so no need to bring the alkalinity down. Also, the calcium is only a tad high (I recommend 350-450 ppm,but a bit higher is OK if alkalinity is not too low) and is not any sort of problem, but if you skip the calcium part of the B-ionic for a few days, the calcium will decline.
