Hi,

I just receive a new batch of K2SO4 from AquariumFertilizer and I noticed a slight difference in the colors when compared to the K2SO4 I have from GLA. The new powder is a little whiter than the old one. Is this normal ?

My K2SO4 is white powder like the powder sugar, even whiter and as fine as it

Hi,

Both powders are K2SO4. I just tested both b/c I was afraid one of them was KNO3.
