now that I have my reactor running like they say it should ph 6.5 inside reactor, i find that my dkh/ca levels have gone way up.
My ca is at 450 ppm/dkh is at 11 is this cause for concern I have been monitoring it for the past few days and it seems to be stable there.
Or should i back off my bubble count to 1 bubble every 2 sec. to bring the ph down so that it is not dissolving so much media

It's hitting the high side (see here for idea of NSW). As for tuning, idea is to keep the pH around 6.5 and if want to lower the system overall, decrease the effluent drip rate and bubble count. Here's a good tuning article.
