I purchased an API SW Master test kit. I figured while my tank is cycling I could practice with it so that I would have the hang of it when I'm able to put in some livestock. One thing I'm never sure about with these kinds of kits is matching the shade of the water with the right shade on the chart. When I hold the tube against the card like the directions say it appears one shade. But if i turn in the light in appears another shade. One way the light is coming through the tube and the shade appears light. The other is still in the light but it's not coming through the tube and it appears darker and more equivilent to a higher result. Is there a trick to getting this accurate so I know I'm reading it right?
