I have the 6 way HTC kit as well, at purchase (just last week, pool filled this weekend), it was the only kit available for me immediately.
If you're referring to alkalinity (TA) and hardness (TH), it's really easy to convert to PPM.
These directions will apply for both, but TA will start green, then turn to red when you've reached the right number of drops, whereas TH will start red and then turn to blue.
Add your water to the 25ml mark on the tube, then add in 5 drops of your indicator liquid, just one at a time, swirling after each drop. The water should turn to the above starting color.
After that, add in one drop at a time of your titrant liquid, again swirling the tube gently after each drop. When you get to however many drops it takes to change the liquid from the first color to the second, multiply that number by 10. The resulting number is how many PPM the test is reading.
For example, tonight my TH took 11 drops to turn the water from red to blue, meaning I have 110ppm of total hardness (11x10=110)
One thing I noticed is a drop or two before it actually turns, on either test, it will sometimes appear almost as a dark grayish clear/colorless, and then change with the next drop or two. Stop when it turns and stays, no matter how the color appears. Red may actually appear more pink depending on lighting etc., it's still "red" when it stays.
I can't help with CYA yet at I haven't been able to test it, my kit was sent with the small test tube cracked in half, ugh
