Maintaining Alkalinity

[cwatkins]

^^ Yes very good link. I use the two part (technically 3 part, but the Mg is dosed by hand whereas the other 2 are automated).

Go to Costco and pickup a pack of 6 little boxes of Arm & Hammer.

One box fits nicely on a cookie sheet and then bake it in the oven for a couple hours to bake out the CO2.

Cheap and Easy! And the little boxes measure out almost perfectly for 1 gallon of mix.

P.S. I went down to the local plastics shop and bought food safe 1 gallon containers. If you get one with a spout on it then you can use that to pour into your measuring cup.
