Hello,
For my current remineralization regime to target a GH of about ~5.5 per 50 liters of water I currently use 4 grams of Magnesium Sulfate and 4 grams of Calcium Chloride.
What I want to do instead, as I am switching over to DIY dosing of NPK as part of my WC water prep, is to blend in Magnesium Nitrate to dose my N for a target of around 30 ppm (this could be 20-25 ppm instead though) and keep my current dose (4 grams) of Calcium Chloride (if that adds up). I want to keep the Ca:Mg ratio to about 2:1 (I am flexible on the ratio).
So my question is how much Magnesium Nitrate and Magnesium Sulfate should I use then?
Based on the info on the Magnesium Nitrate product I am going to use 13 grams (seems like a lot?) of Magnesium Nitrate should reach 29 ppm of Nitrate and 25ppm of Magnesium, which leaves room for 8 ppm of Magnesium from the Magnesium Sulfate or about 1 gram? In other words, for 50 liter of water, adding 4 grams of Calcium Chloride and 13 grams of Magnesium Nitrate and 1 gram of Magnesium Sulfate will yield a GH of ~5.5 at a 2:1 Ca:Mg ratio and 29 ppm of Nitrate.
Also will this mixture still be adding enough Sulfate?
Cheers,
Michael
