Try dosing kalkwasser... should balance what ca/alk levels you are at while raising your PH... another thing is making sure that there is adequate ventilation in the room(open windows, fans, etc). You're not using a calcium reactor yet... are ya???
BTW dosing too much kalkwasser will raise PH to dangerous levels. I dose with evaporation a kalkwasser solution(lime/ro water) with a ph(supersaturated... not a slurry) of 12.5 .
