Can someone please tell me the perfect level of kh in a marine tank,I've been told its the most important one to test.
Here's a question on the kits...I use the API kit (yeah, I know)...and after 8 drops, it turns from blue to a green-ish hue, then after 9-10 it turns completely yellow. Is the reading supposed to be taken when it starts to change from blue, or when it turns all yellow?
