Raising Calcium?

What tests are you using? Are they in date? what is your pH?

I use Dow Flake and or Pealeadow mixed at about 2 cups to 1 gallon of R/O water and add 1-2 coffee scoops with my top off. When adding this mix you need to watch your calcium levels closely because it might take awhile for your cal. to start climbing but when it does it will climb fairly fast and as it starts to climb it will lower your alk at the same time. This works for me but like I said if you do it watch all your levels closely.
