rather than continuing to mix minerals I just cheat now and purchase GLA's ultimate booster for the convenience

I use a milligram scale for all my measurements, but you can round off.

You can use APC Fertilator or type rota.la into your browser for wet's calculator to figure out what dosage is needed to achieve the levels for your size tank.

GH:
CaSO4 = 32.148ppm
MgSO4 = 6.52ppm

KH:
1~2 (approx .032g Baking Soda raises 1 Liter to 1KH)

1gal = 3.785L

So for example, to raise 10gal to 1KH then (37.85L x .032g)= 1.211g Baking Soda.

I mix tap water with RO at a 3:1 ratio. I end up with ph 7, gh 5 and kh 5.
