Hi jstigdon and welcome to TFP!
You, my friend, are ahead of the game! Way to go with the TF-100 test kit!
Since you've researched enough to know that the proper test kit is the key to your success, I'm guessing you've read up in Pool School and understand Pool Math??? Just in case, here's some links:

Getting Started It's a big help if you can put some pool specifics into your signature.

ABCs of Pool Water Chemistry

Extended Test Kit Instructions Since your CYA measures 100, I would do the extended test to see where it truly lies.

Back to a sparkling oasis! With that lovely shade of green going on in your pool, I would read this article as well.
PH 7.5; This is decent but if you can get it to about 7.2 with MA it will be better for your SLAM
Calcium Hardness 125; Depending on pool type this may or may not be ok. Vinyl liner pool - dont worry about it unless it's high and yours isn't.
CYA 100; - This is worrisome because the actual number could be much higher. Perform the extended test and report numbers here. Then we will talk water replacement.
FC 1.5; - obviously low. you need to add chlorine. the problem is we don't know how much until you get a good cya level to start.

How to chlorinate your pool Chlorine is chlorine is chlorine. It will all sanitize. It's the mode of delivery that often creates problems. Until you get that CYA under control, liquid bleach/ liquid chlorine is your friend.
CC 0.5; - indicates a problem because this is the byproduct of the chlorine taking care of business. With green water, you got a lot of business to take care of.
TC 2.0; and
TA 180. - don't be concerned with this at the moment. we will get to that one day when you're staring at your sparkling clear water and want something to do because you're bored.
So, in summary, you have a green pool eating you out of house and home in chlorine. You need to adjust the pH and then SLAM the pool. SLAM is shock level and maintain. Maintain is key. SLAM is a process with a beginning and ending from hours to days.
