Hi ,

A KH test does not have a colour chart. Just count the number of drops from the time the water is blue until the time when the it just turns yellow, and that is the degree of KH. It does have to be a certain shade of yellow just when it turns yellow, double the amount of water if you want the degrees is 0.5, i.e. 1 drop = 0.5 degree.

If the solution is yellow at first drop, it could mean that there's no KH in your tank water. Time to boost up with baking soda or some seashells.

Try with water that has some baking soda in it. It is alkaline and the solution is blue at first drop.

I posted this some time back

The only time i have a change in color is when im preparing for my dropchecker solution 4dkh, it will remain blue till after the 4-5 of KH drops and color will change back to yellow.

If you want to see for yourself, just drop 1 pinch of sodium bicarbonate into water, extract 5ml and test it.

Thanks Ronang, juggler and torque for ur help.
I was looking bright yellow as descriped in the instruction manual.
Just now i checked baking soda solution. Yes it does turn blue at first drop.

My Tank and tap water has 0 KH

I have PH tester and KH tester, is it possible make a diy CO2 tester out of what i have with me.
Saw posts from torque.. and there u talk about 4KH solution. can i know how to make 4HH solution?

[torque6]

can google the recipe online, its just a mixture of water+sodium bicarbonate. The kh test kits comes into play when deriving the drops required to turn your mixture to yellow with 4-5 drops.

Thanks torque, I managed to make 4 KH with the help of my friend..
now the drop checker is doing great...

Thanks once again for all of your valuable posts
