My PH this past week dropped to 7.6 I added lime water (didn't see much of a difference) and went back down after about a day.
I added some more alkalinity and now that reading is 14. My calcium is 460. I do not run a calcium reactor nor is the tank a BB.
For my reading of the PH I am using the lab grade PH pen along with the Aqua Controller JR. Question here...it may be dumb, but adding ozone to the tank, will that make any difference?
