Calcium problems.

[StirCrazy]

Ok, sence my suplement is being shipped and I had a few extra days to play and try some of your sugestions, I increased the bubble count on my reactor from 60 bpm to 90 bpm.
befor I di dthis increas my levels were

Tank
KH/Alk 10.7 dKH, Ca 210, Mg 860 ppm

effulent
KH/Alk 27 dKH, Ca 310

48 hours after increasing the co2

tank
KH/Alk 17.6 dKH, Ca 225, Mg 930 ppm, PH 7.9 (at night time)

effulent
KH/Alk 48 dKH, Ca 410, Mg 1050 ppm, PH 6.4

I am going to leave it like this for 2 more days and take another set of readings then, My only concern is the Alk reading of almost 18 dKH... is this a problem?
