Thank you guys for your replies to my problem. I did dose high with bleach, the pH was good, and the algae is still not reacting. And it has stained some areas of the gunite surface. I'm going to drain today, power wash (delicately) to remove the algae and refill. I don't have a problem monitoring and adding BBB when necessary but I do have a problem brawling with this extreme CYA. Here in North Texas the summer sun is brutal and I can't see starting out with algae growth!

If you would please direct me to one or more of your links or a good post on starting up a pool with fresh (tap) water using the BBB program.

Thanks very much,
Keith
