First of all, you don't have bromine in your pool. Glad to hear the pool is clearing. Keep adding bleach. You still need to raise it to 15 for a few more days to be sure you kill all the algae. Most testers don't get past 5. The one Ben sells at www.poolsolutions.com does and that is why it is so great to have it. In the meantime, you can make your tester read higher than 5 if you dilute your sample. Take one part pool water and one part distilled water, mix, test as usual and then multiply the result by 2. If you need to go higher, take one part pool water and two parts distilled water, then multiply by 3, etc.

Be sure you don't use any cal-hypo for your chlorine. Your calcium hardness is already pretty high and that might make your water cloudy.
