4dkh Solution

What Mr Anthony(Darkblade48) described in his link looks somewhat cumbersome to make 4dkh solution.Will any one tried simple method using PH solution and baking soda.

You can also make a 4 dkH reference solution using a kH test kit and baking soda.

Just add a very small amount of baking soda to distilled water, test it, and repeat until you achieve 4 dkH.

4dkh solution

Sir shall be glad if u could furnish me the details .Mine there is no problem in the tank but for academic interest iam asking.As long as fishs are comfortable and plants growth are visible we can guess sufficient Co2 is inside the tank as a lay man's guess.

Perhaps you are referring to this one:

This is the method I use, with analytical grade reagents and equipment. Of course, you can substitute with regular sodium bicarbonate, etc.

A very small amount
I think my first batch would have tested in the 1200 range

yes Mr Anthony ,what u have refered was the link i saw.As i keep Guppies,Angels,and redswords.No precise measurement of Co2 is required as they can withsand some what plus or minus.Not like discus fishes which are prone to senstive environment.Do u keep Discus fishes Anthony.What is ur comments Mr Anthony just to keep Discus with angels.Not interested to breed,which is also difficult in our country water parameters.
