First, let me say I LOVE this site. It has helped a newbie tremendously. We have a 27ft ABG pool. It took 17,300 gallons to fill it up. Used it for about 6 wks last year as we bought late in the season. When we opened it this year, no problems. Until now. We definately have/had mustard algae.

For the past 4 days I have kept the FC levels above 20ppm. Water is clear now but still has some brownish spots on the bottom. Have vaccuumed and brushed the sides. We run the pump, a 1.5hp pump on low 24/7. On high for 2 hours after adding the liquid bleach. Tonight my levels are as follows (no 6% bleach added since last night):
FC 26 CC 0 ph 7.2 Alk 75 CYA 80 I test with a Taylor K-2006 FAS-DPD kit (which I love).

Have I left the chlorine levels up long enough to kill the mustard algae? Should I now keep my chlorine levels above 5-7 ppm? Should I add polyquat when the chlorine drops back down some? What about flock? Should I soak all the noodles, floats, vaccuum hoses, etc in bleach before putting back in the pool?

Sorry for the long post with so many questions but I just do not want the algae to come back. Would like to enjoy the pool since it is the perfect weather for it. Thanks so much in advance for any help you can give me with these issues.
