4 dkh solution - Equipment

How do you make a 4dkh solution for a drop checker? I have R.O. water. Does anyone sell this solution?
I would really like to know how to make it though.

Here you go. You don't need graduated cylinders. I used measuring cups and they worked fine.

You're welcome

Works the same as a commercially prepared solution, but 100% cheaper. I tested both solutions side by side with my c02 drop checkers - no difference at all. The home made solution is not totally plug and play though. You still have to purchase the PH Reagent solution and add 3-5 drops in the solution when you place the solution in the c02 drop checker. However, costwise even with the purchase of a PH reagant solution, it is still 100% cheaper to make your own.
