Ummm, yeah, I think you overdid the bleach a little. Adding 12 gallons to a pool with this volume would have added approximately 48ppm of chlorine! I hope your liner isn't toast!

Obviously, don't add any more bleach for awhile. As Carl said, you do ultimately need to get a good kit. As a temporary measure only, you can use a dilution method to force your current kit to read higher readings than 5ppm. More info about that here:

I'm assuming by CA you mean CYA? If so, then your CYA is really high. I'm assuming that you have been using trichlor pucks for quite a while, maybe even for several seasons? They cause CYA to build up over time and that is how people get CYA levels like you have. The only way to lower it is to do a partial drain and refill but you do NOT want to totally drain a pool. Your other option is to keep the high CYA and just run higher than normal chlorine levels. Take a look at the Best Guess chart in my signature below for more info. At any rate, NO more pucks in this pool or dichlor shock. Both of these are stabilized forms of chlorine which will continue to add CYA and that is something you do not want.

Hope this info helps. By the way -- welcome to the Pool Forum.
