That bottom one says heptahydrate dont know what that means also there is so many choices i am struggling. Seems cheaper doing it through amazon or ebay at the moment to be honest did you use them exact salts @plantnoobdude

I use hexealchemicals as well, 10kilo bucket. Lasts for a while 😂
As far as I'm aware the heptahydrate is the only way the salt can be stored, @dw1305 answered my queries on that before.
 
Thats crazy I was going to pay that for 1kg only trouble is I will have to put in shed to store do you buy all dry salts from that seller ? Thanks again everyone

heptahydrate basically means there is crystal water in the salt. Mg (magnesium) SO4 (sulphate) 7H2O (water). MgSO47H2O
as magnesium sulphate is not pure magnesium. by weight MgSO47H2O is around 10% pure magnesium.
 
I am trying to cancel ebay order as don't need 10kg also £2.50 at loyds pharmacy so will get this thanks mate
