I used to use baking soda, but even when mixing with DI water, I'd get this weird chalky precipitate at the bottom of the container. The tropic Marin stuff doesn't do that. It is expensive, however, and if Tim considers 128 grams/day low, I might have to switch.
Tropic Marin recommends dissolving 420 grams of the alk and 380 grams of the calcium in 5 L of water. At 540 mL a day and rising, I'm burning through my 3 gallon dosing containers pretty fast. How much do you think I could increase the concentration of each without risking supersaturation precipitation?
