Green Leaf Magnesium Sulfate (MgSO4)

[Marcelo]

Hi Everyone, 

I have been using Green Leaf fertilizers and EI in my planted tank for a while (N,P,K and Micros)

As I use RO water for TPA, I usually adjust the KH with Seachem Alkaline Buffer and I mix 1/2 gallon of my Tap Water to adjust the GH (I am from Florida - ver hard water here).

I just saw I have a bag of Magnesium Sulfate (MgSO4) that I never used !!! It came together with my EI kit.

Is the Magnesium to be used instead of the Tap Water that I use to raise my GH ? Or it will raise the GH and KH? 
 

thank you very much

Only raises GH as the Magnesium part and adds sulfur.

Just a point of intrest, the sulfer in the magnesium might lead to perception IF you are using it in a solution,   resulting in a weaker solution than calculated.  I found this out on the barr report when I posted a question about the Rotalabutterfly fertalizer calculator.

@Mmiller2001 but replacing the tap water mix with the MgSO4 is worth or the tap water has more stuff on it that the MgSO4 doesn’t ? I am already dosing dry K,N, P and Micros … I would prefer to use MgSO4 as is to easier and safer …

@JoeQ sorry .. I didn’t understand what you meant …

You would need a calcium source if you go full RO or distilled water. GH is a combination of Ca and Mg.
