I definitely agree with Amphiprion, but if you need to do any tests in the mean time these will give you a rough idea of where your perameters are at, but I wouldn't rely 100% on these shades because holding the original cards up to the screen and comparing them to the pic they were very slightly off. Oh and it looks like my scanner cut off the highest or darkest shade of each card but your tank shouldn't be anywhere near those colors anyway.
I lost a color card in the past for an API test kit. They sent me a free replacement, no questions asked. I'd definitely recommend getting in touch with them.
