Hello everyone,
Today I wanted to play a little bit with drop checkers, so I went online on wet's calculator below:
http://dropcheck.petalphile.com
What I'd like to have is a drop checker that turns yellow when my co2 reaches 40ppm. I think yellow is easier to see than green, at least for me, so I wanted to check that option.
So, here is what I have done:
1. Entered 40 as target co2 ppm.
2. Left margin of error of +-5.
3. I chose to mix in 1 liter DI water.
4. I checked the yellow option.
5. I checked one drop checker.
So, with the above input, wet's calculator tells me to add 159.2 mg of baking soda do 1 liter of DI water to have a solution of 5.31 KH. Then add that solution to my drop checker, add 2 drops of Bromithymol, and the checker should turn yellow when Co2 concentration reach around 40ppm.
Ok, now get back to the calculator form again, and change the color option from "yellow" to "green"... Well, you would expect different instructions, instead you still get the exact same dose (159.2 mg of baking soda per 1 liter of DI water to have a solution of 5.31 dKh). Why's that??
Also, try the "two dropcheckers" option, with the "yellow" option checked, and you'll get a completely different recipe for the first drop checker which should target 45ppm of co2: 45 mg of baking soda per 1 liter of DI water to reach a solution of 1.50 dKH.
Now, get back to the calculator form, then enter 45 ppm as target, leave the rest as it is, and check "one drop checker".... Well, you'll get a different result than the suggested dosing for the first drop checker with the "two dropcheckers" option just tried above:
179.1 mg of baking soda for 1 liter of DI water, to reach a dKh of 5.97.
Well, I can't understand the sense of a such mismatch between results. Can you?
