Well, if you added bromine, you shouldn't have added chlorine. They are two different systems. Your test kit really needs to be replaced as the reagents are too old to get an accurate reading. If you have too much chlorine, sometimes it will bleach out the reagent.
I would take a water sample to your local dealer and have them test it for you. They will tell you exactly what you need to do. They'll have fresh reagents, so you will get accurate readings. Their system will probably even be computerized.
At the worst, you could dump and start over. Really won't cost you too much $$ to do that. Sometimes its cheaper to do that than start dumping a lot of chemicals in. If you do that, take your tap water to your dealer and have them test that. That way you'll start out doing the right thing.
Good luck.
