just flush the container with tap water and thereafter take 5ml of yr tank water and drip the solution one at a time and shake it before another drip first drip will turn the water blue and then drip it till it turn green and then another one more drip it'll turn yellow stop the drip when it turn yellow count your drip if it is 7 that the 7dkh if 9 drip it then 9dkh
