Seachem Reef Advantage is Calcium Chloride, Magnesium Chloride, and Strontium Chloride.
Seachem Reef Builder doesn't have published ingredients, but based on the appearance, instructions and brief testing it appears to be Sodium Bicarbonate (baking soda).
While less expensive, it is certainly not as complete a supplement as any of the two-part additives. For comparison, the two parts of ESV B-Ionic include ions of: Carbonate, Sodium, Bicarbonate, Sulfate, Borate, Fluoride, Iodide, Molybdate, Vanadate, Selenate, Chloride, Calcium, Magnesium, Potassium, Bromide, Strontium, Lithium, Barium, Rubidium, Iron, Zinc, Nickel, Copper, Manganese, Cobalt, and Chromium.
Kent Tech CB and TLF C-Balance are virtually identical to this.
However, my main complaint about the SeaChem products is that they are not packaged or labelled for the aquarist to easily dose the right amounts to maintain ionic balance. With the two part supplements as long as you dose equal amounts you know that your Chloride to Sodium ratio is correct.
For ease of use, the two-part supplements are it. If cost is the main concern and it's a relatively small tank then kalkwasser is by far the cheapest. And for a larger tank, a calcium reactor, like Bodine suggests, will quickly pay for itself.
