I just sent out the info for both Greg Watson and Aquaessentials to see about them selling the KH solution for folks.
You add 3.484 liters of DI water to this 10mls smpale to get 4 KH(total will be 3.499liters).
If you miss the milliliter volume by say 2 mls, you will get an error of about 0.02ppm of alklalinity.
I'd suggest buying a 500ml volumetric flask(run about 5-10$ on ebay etc), making up a batch, use 7 full jiggers of the 500ml flask, take out 16mls with a small cheap pippette as best you can. Place the stuff you plan on using in the 500ml flask and keep and use from there.
The rest of the 3 liters, store in a sealed jug, milk jug etc and clean it out really good. Fill up when you need more or sell off.
Note, this will last about 26 years per drop checker, based on 2-3 week use and 5mls used each time.
You no longer need to do pH test kits(other than filling once a week) or KH measurements. You get a lot more information out of the pH test this way as well, you see the pH change/CO2 all day and night long, not just one mere snap shot in time!
