Hi bros anyone using Tetra brand test kit for KH? The water turns from blue to green then to yellow with every drop I put in. So which is the correct reading? The moment it turns green or turns yellow? Thanks!

Ya bro but before turning yellow it will b green 1st. So kinda confused which reading to take. The moment it turns green or the moment it turns yellow? Will b switching to other brands after finishing this.

the moment it turns yellow would be correct bro, i compared readings with salifert....

the correct reading should be turn to yellow and not turn colour(blue green)

based on different test kit

cheers
