OK next question...
I have a Red Sea KH/GH test kit. In testing KH it says:
Get 6ml's of tank water in the test tube.
Add 1 drop of KH indicator and mix.
The Color should match the starting color of the card.
Keep adding 1 drop at a time and checking the color until it matchs the end color.
Now when I measure my water it never shows me the start color. Which is a blue color. It only looks like it is lightly tinted the end color which is somewhat orange. Now If I continue it looks like my KH is around 3 or 4 but I am thinking that if I cant achieve the start color then my reading must be off. Any ideas? I am now injecting co2 and am not in the mood to kill my fish.
