1 table spoon? are you sure am reading this correctly? you are looking at 309 ppm Potassium and 22 dkhHi!
How much is TDS raised using potassium bicarbonate e.g. 1 tbs on 5 gallons of RO water?
Thanks a lot.
Okay, 0,1 tbs. Doesn't matter, because this is just an example. I'd like to know about influence potassium bicarbonate to TDS ^)1 table spoon? are you sure am reading this correctly? you are looking at 309 ppm Potassium and 22 dkh
1 table spoon is about 15 gram KHCO31 table spoon? are you sure am reading this correctly? you are looking at 309 ppm Potassium and 22 dkh
@M.eremin do you have TDS meter? so what was your main purpose behind the question? are you raising the TDS for shrimps or something else? let me know if I could further help you with anything.
I'll need to find it, but there is an index of conductivity for fertilisers, that relate them to the index value, which is sodium nitrate (NaNO3).Now I'm analysing the influence different solids and salts on TDS.
How can I calculate it by myself?

for example: if you were to use K2SO4
add 1.265 gram K2SO4 into 5 gallon
this will add 30 ppm K and 12.3 ppm S
convert S into SO4 by 12.3 x 3 = 36.9
30 + 36.9 = 66.9
TDS = 66.9

for example: if you were to use K2CO3
add 1 gram K2CO3 into 5 gallon
this will add 30 ppm K and 23.02 ppm CO3
30 + 23.02 = 53.02
53.02 TDS
there are many different ways to do this, I hope this helps. you can also use this same formulas to make your stock solutions or recipes.
nope, just some simple mathematic and chemistry knowledge/Skills and most calculator does the rest for you. I have further updated the post #10WOW! Are you autor this program??
Unbelievable....
Thank yo so much!Long as you know the chemicals and their %
these two link is all you need:

lets assume you want to make a stock solution while using KHCO3
KHCO3 contain 39.0533% K
we are going to Mix KHCO3 in 500 ml Solution
and dose 20 ml from this solution into 5 gallon RO water (18.9271 liter)
this will add 1 ppm K into your 5 gallon RO water
Formula:
100/39.0533*500*1/20*18.9271/1000
google that or calculate it yourself and it will give you the needed grams which is 1.21 grams (1.21161976069 grams to be exact)
lets assume you want to directly add KHCO3 to your 5 gallon (18.9271 liter) RO water
KHCO3 contain 39.0533% K
this will add 1 ppm K into your 5 gallon RO water
Formula:
100/39.0533*500*1/500*18.9271/1000
google that or calculate it yourself and it will give you the needed grams which is 0.048 grams (0.04846479042 grams to be exact)
