![]() Just want to check my numbers here. I am going to be mixing my solutions in 2 litre jugs. So all my ingredients are cut in half.
Calcium - 1 cup Anhydrous Calcium Chloride Alkalinity - 1 cup Sodium Carbonate Magnesium - 2.5 cup Magnesium Chloride 1.5 cups Magnesium Sulfate or 4 cups Magnesium sulfate As for the Magnesium solution is one mix better then the other? Thanks. |

![]() I can't verify the quantities right now... But as for the magnesium, most people use the one with two ingredients. That all sulfate recipie would only be a minor concern if you never did water changes as sulfate levels would rise. Sulfate is still a major portion of the 2 mag recipe anyway

![]() Ok got my doser setup to dose Calcium and Alkalinity but have a question about magnesium. J&L sell Magnesium Chloride or Magnesium Chloride Flake. The two are the same thing just in different form, so why is here a price difference between the two? Do you have to weigh the flake? or can it be measured? Does the flake dissolve as well as the powder? Is the price difference worth it? Thanks all.

![]() When you get the mag chloride, get some mag sulphate (epsom salt) from costco. Its the cheapest. Mix as in the given recipe above.
Sorry, I don't know the difference betw. the powder and the flake. |

RHF wrote this article when calcium reactors were THE thing. 2-part dosing is more common now though, and we add a lot more chloride ions through calcium choride, so a better version for 2-part particularly if you are dosing calcium chloride heavily is 5:3 chloride to sulfate to make up for all the chloride we're adding via 2-part.

![]() I use this recipe from Randy Holmes:
3. Using both Epsom salts and MAG flake, dissolve 7¼ cups MAG flake and ¾ cup Epsom salts in one gallon of water, and use that to supplement magnesium in amounts determined using this linked online calculator, with the entry "Randy's Recipes 1 and 2 Versions A and B," and ignore for this purpose what those designations mean. This recipe is preferred, but its advantage over recipe #2 is minimal in most cases. Which is derived from: http://reefkeeping.com/issues/2006-07/rhf/ |
