How do I lower the alk coming out of my reactor?

My alk keeps going up and my calcium keeps going down. Right now I am doing 30 BPM and dripping 25 ml/m. Do I raise my bubble count to bring the pH down to get more calcium less alk?

I belive that you lower your bubble count. The higher the CO2 the lower the PH. With the lower PH that will let your ALK drop. But Im not 100% sure on this Im sure someone will chime in that will know for sure.

I was under the impression if you lower the bubble count the pH goes up and it raises the alk but lowers the calcium since you are putting more o2 in the system because it doesnt break down the media as fast. So if I lowered the pH in the reactor it melts more media which raised calcium output.
