Two Part Calcium & Alkalinity

[Tarazed]

What are the components of most of the two part "supplements" out there? Are they Sodium Bicarbonate and Calcium Chloride? Trying to find the cheapest two part method. www.bulkreefsupply.com sells the above with a magnesium additive. The website does not seem to say what type of magnesium salt they are using. Obviously its not pure magnesium.

Thanks

The magnesium for three part dosing is a mixture of Magnesium sulfide (Epsom salts) and Magnesium Chloride (Ice melter) you need both parts to balace out the ions and to not put in too much sulfides.
