Green, Cloudy, Dirty, I got it all in my salt water pool?

Thanks Water Bear,

Well I got the $47 Leslie's kit that did all the things that I would need? According to what I have read here in the forum, FC, TC, CC. PH, TA, CH, and CYA. I will order the one from the site too, but I figure I needed this in a hurry. They have one for $84, but that did the other test that so far from what I read here is not needed , hopefully that is?
For the FC test it says fill small tube to the 9ml line and add 5 drops DPD Reagent #1, 5 drops DPD Reagent #2, then invert and match to color chart.
This is your FC reading
then it say add 5 drops reagent #3 and invert and match to color chart again, and that's TC?
Correct, this will be either the same as your FC reading or higher. (the color will either stay the same or turn a deeper pink.) If your FC reading was 3 ppm and then you add reagent #3 and the color deepens to the 4 ppm reading then your FC is 3 ppm TC is 4 ppm and CC= TC-FC=4-3=1 ppm.
which is lower? then it says to subtract FC (Which is the higher number?) from the TC (which is the lower number?),
There is no way the TC (reading after reagent #3 is added) can be lower than FC (reading after reagents #1 and #2)! The TC reading will always be equal to or greater than the FC! When you add the third reagent to the tube the color will either stay the same or get deeper pink.
and that gives you CC, but a larger number from a smaller number always gives you a negative number correct? I guess you just suppose to ignore the negative?

TC will always be equal to or greater than FC!
