Testing Water

[brendac]

I have a question about testing my aquarium water. When I compare the color in the test tub to the color on the card... do I hold it right against the white on the test card or just a little away? cause when I hold it against it... it is darker then when I hold it away of coarse.

What kind of test kit are you using?
Most kits tell you how to read it in the instructions.

Yep, that is what you do for Aquarium Pharm. Salifert test kits are the opposite.
