Missing the instructions on your test kit. Here is a refresher.
Solution 1 (yellow)- No longer available now DPD1 Tablet
Solution 2 (red)
Solution 3 (clear lid)
Solution 4 (blue lid)
Solution 5 (green lid)
Fill small 10mL container and drop in one tablet (DPD1).
Solution will go purple to indicate chlorine.
Fill the other vial to the high mark.
If there is a high chlorine level add a couple of drops of neutraliser (solution 5). If normal, add 1 drop.
For 10mL containers add 2 drops of phenol red (solution 2), 25mL containers use 5 drops.
Solution will change from yellow to purple to indicate pH.
Complete pH test as indicated above.
Add, by the drop, solution 3 until the solution changes to the ideal color.
In a 50,000 pool for each 2 drops it requires to bring the pH down to the correct level add 500mL of acid.
The large pH containers often have a lower mark for alkalinity, otherwise use a 10mL container.
Add 2-3 drops of solution 4.
Add, by the drop, solution 3 until the solution changes from blue to clear or yellow.
Multiply the number of drops of solution 3 used by 10 and this is your total alkalinity level.
