120 PPM Alkalinity Solution - Dillute to 4 DKH

[RlxdN10sity]

I have a bottle of 120ppm solution that was sent to me by Lamotte. How much do I need to mix with DI to obtain a 4DKH drop checker solution?

120 ppm of KH equals 6.72 dKH. The volume of DI water needed to add to 100 ml of 6.72 dKH water to get 4 dKH water is 68 ml. That gives you 168 ml of 4 dKH water.
