Quick maths check please.

Hi all.

I picked up some JBL K to dose my tank as K is low.

Instructions are 2ml per 100 litres will raise K by 1mg/l/ppm, so if i want to add 15ppm to 30 litres i need to add 9ml. is that right? Sorry, I know this is very basic stuff, but maths is a very poor subject for me and i want to make sure

Also, does anyone know what salt JBL use in this product? I have potassium bicarb which I know is a lot cheaper but I am trying to keep my KH as low as possible.

Yes mate the maths is correct. Unsure on the product itself though so can’t help with that.

2 / 100 x 30 x 15 = 9ml

or

or

for when the fert runs out

Thanks all.

@zeus, yes I will definitely be picking up some chemicals, I just picked this up as I could get it right away.
