I assume that you meant 3 jugs (121 oz. each) rather than 3 gallons. That was fine to add. Also adding dichlor as well is probably going to make your chlorine pretty high. If you still haven't received your Taylor K2006 kit, your 6-way kit isn't going to be able to register that high. However, since the 6-Way kit has an OTO chlorine test in it, you can use this chart to kinda estimate what reading it is showing.

Also, with chlorine above 5ppm, you won't get an accurate pH reading, so don't bother testing it right now. (When you are using the K2006 kit, the pH test is valid as long as the chlorine isn't above 10ppm.)

How did you add the stabilizer? Don't run the CYA test today. CYA takes awhile to fully dissolve and show up in a reading so you'll just be wasting your reagents if you test again too soon. The amount you added should have increased your CYA by about 10ppm. That, plus the dichlor you added, may put you at just about the right place for your CYA level. For now, don't add any more CYA or dichlor until we get a good reading on it in a few days.

You're on the right track!
