Hello Folks i have made a Diy drop checker and 4dkh water.Also i have an API ph 6.0-7.6 ph test kit but the regent is red not blue is that a problem

Cheers Mick
 
My CO2 reagent is yellow..... until I put it in the drop checker. With the 4dkh water it goes blue straight away and then goes green after a couple of hours in the tank. (Right now its pale green and the plants are lurvin it)
