According to the instructions "Each 5 g/80 L will raise magnesium by about 5 mg/L. " So that's 19g/300 liters will raise the magnesium by 5ppm. I'm getting that you'll need 1.52 kg, not 1.25. Magnesium sulfate is a common alternative. AKA epsom salts. It's relatively cheap. Quote Link to comment Share on other sites More sharing options...
RUNAS Posted September 28, 2012 Author Report Share Posted September 28, 2012 Thanks Ira, Math not my strong point :slfg: You should change your name to IRD, thats how they work, you work your tax and they tell you it more !!! :facepalm: :sml1: Im kidding. I will get some Epsom salts on Sunday, it has to be cheaper than $57 for 1.2kg. Using Epsom Salts are the mixing quantities the same/similar to Seachem? Thanks again.

GrahamC Posted September 28, 2012 Report Share Posted September 28, 2012 If 2 kg only raised the Mg from 700 ppm to 1000 ppm, then another 2 kg should only raise it to 1300 ppm ? Quote Link to comment Share on other sites More sharing options...

livingart Posted September 28, 2012 Report Share Posted September 28, 2012 Magnesium Chloride Hexahydrate (MgCl2) also known as "Magflake" (or other alternatives) If mixing MgCl2 its solubility in water at 20°C is approx 170g per 100ml of water Quote Link to comment Share on other sites More sharing options...
