You really need to bite the bullet and order a good kit --- Taylor K-2006. With a CYA level that is through the roof like yours, you will have to run extremely high chlorine levels (per the Best Guess Chlorine Chart in Ben's sig above). The HTH 6-Way kit and an OTO kit only measure chlorine to 5 and aren't going to help you.

You did the right thing turning off the chlorinator but you are not adding big enough doses of bleach to accomplish anything since the CYA is so high. In your pool, each gallon (4 qts.) of 6% bleach will add just under 4ppm of chlorine. As you can see from the Best Guess Chart, your shock level is going to be around 25ppm, so the 3 gallons you added is not taking it high enough. Keep adding bleach every time you test and get back to 25ppm. Continue to do so until you can go from sundown one evening to within 2 hours of sunrise the next morning without losing more than 1ppm of chlorine and the water is clear. Then, keep it high for one additional day. After that, you can let the chlorine drift down but must always keep it between 8-15 ALL the time or you'll constantly be fighting algae. No more trichlor pucks nor any type of dichlor shock powder in this pool!

Your pH is fine where it is so don't worry about more Borax at this point.

Order the good kit. In this pool, it really isn't an optional item but a critical one or else you'll have a very difficult time managing this pool.

Hope this helps. Good luck.
