How Much To Dose ?

[MrMarine222]

Hello,I need a favour I am using reef foundation liquid supplements. Today I checked my magnesium level it was on 1170ppm I want to bring The magnesium level to 11350 ppm. I need to increase 180 ppm. The bottle says for 100 litres only it will increase by 1 ppm. My tank is 400 litres. So do I have to add 180ml it saying I have to add 180ml . I am a bit confused . Can you please help me how much do I have to add.

Take it it's the Red Sea foundation C your using?
If so, 1ml will raise magnesium by 1 ppm in 100 litres, (4ml in 400 litres)
You can raise mg by 50ppm max per day, so 200ml per day for 3 days and 120ml for 1 day.
Personally I wouldn't raise it so fast, divide everything by 2 and do it over 8 days instead of 4. And test before each dose.

You either need a bigger bottle or more bottles,
by far the cheapest way is to use a powdered buffer, the bottles are really only any use for smaller systems
