quick math for ya...
assuming you got 1 gallon of water...
5 pints = 10 cups
8 pints is a gallon therefore 16 cups
for every cup you'll need a 1/4 cup of fresh from your gallon. you'll have 6 left.
10 X .25 = 2.5 or 2 1/2 cups from the gallon. that leaves you 3 1/2 cups to drink.
you'll also net yourself 12 1/2 cups 4dKH. that's 3 quarts and 1/2 cup.

long process huh, but writing it helped me through the thought so i'm leaving it. point is you can measure out 3 quarts and 1/2 cup and mix that with 1/16 tsp of baking soda.

i did the math for all of them and this is what i got...

1/2 tsp bs, 6 gallons and 1 quart h20...
1/4 tsp 3 gallons and 1 pint...
1/8 tsp 1 gallon and 9 cups... or 1 1/2 gal, 1 cup...
1/16 tsp 3 quarts and 1/2 cup...
1/32 tsp and 3 1/4 cups

i asked about it here: (http://www.aquariacentral.com/forums/showthread.php?t=199582) as i thought it was appropriate.

and that is the final formulas for 4dKH as far as i see.

Whew! Thats a lot of math :)
I think I get it now....
lets sat 1/16 bs, I would need 3 quarts of dis. water and a 1/2 cup of water to make 4dkh. Or is it the other way around? (thanks for all this math help I'm still in summer mode)

this is a little cleaner:

so yes... but make sure all your water is distilled or 0dKH to start with.
that's why i did the math for you. it's straight forward now. dump in all the water... dump in your baking soda... mix... good to go!

no problem... i did a little more math to be a little more precise. the original number was .48 tsp. that's 96% of a half a tsp. i figured i could get my water closer than my teaspoons so i took 96% of that. i kept my original stats in there. i did notice i put cups instead of pints in the last column also. i have actually been banging my head against the wall from time to time myself wanting to know this, so no biggie. a drop checker is on my list now and i've actually finally started building my hood so that's a benefit. :p:

anyway here is the corrected pic... and it's finally final :clap::

oops again... that last one is .23875 cup, not .119375... never mind, fixed now

4dkh drop checker solution - http://www.greenleafaquariums.com/co2-drop-checkers/kh-standard.html

a little bit of money and some advil and your headache is gone!
i think it's worth it. if one of us can come up with a reliable way to make 4dkh in small enough quantities with things we would normally have then the rest of us can stop throwing our money away one at a time. i mean cummon... $12 - $20 for a pint of water? i'm not paying that when armageddon hits. i found 5 dKH easy enough when i needed it. i can do this too... i think. :duh:... :hypnotized:
