Calcium/alkalinity products

Yes I can see that i would probably go liquid if i had a smaller tank. I must have overlooked that part of the original post when commenting. Although I find it quite easy and cheap with powder so once hitting that tipping point on tank size I would not hesitate in changing.

It is a valid approach. I don't know if I would bother to mix powders either if I had your size of tank :-)

For instance I just used the calculator to calculate that it takes .9 tsp of baking soda to raise the alkalinity of a 20gal from 8 DKH to 10. Just under a tsp of baking soda can be dissolved in less than 1 cup of water. Its simple, inexpensive and better for the environment than buying small plastic bottles.
