Converting from Baquacil to Bleach!

Finally can post a thread, so here are my results and some questions.

Pool looks green but I can see the bottom. Swept pool yesterday and tonight. Cannot seem to get the FC reading to FC=15. Should I add more than 20 gallons of bleach?

Question on K-2006. When I add the 2 dippers of R-0870, the water immediately turns pink. I add the R-0871 dropwise until it looks to be colorless. Then I set the tube down to make my notes. When I look at the tube again, it is pink again. Is this normal? Should I stop adding drops once it turns colorless the first time or should I add more drops until it turns colorless again? Experimenting, I let the tube set for about 10 minutes with the 2 dippers of R-0870 in it, then added the R-0871 until it was colorless and this time it did not turn pink again. Is this acceptable?

Thanks for your help!
