First, thanks for this incredibly helpful website and forum. Second, please advise. I'm resuming the management of my pool after going through 3 different, disappointing services over the last 5 or so years.
I have a salt-cell generator, but when I hired the first "pro," he convinced me to just use chlorine tablets (rather than replacing the cell). Consequently, my CYA is very high. After reading your website, I understand now why the shock that my most recent pool service added, did nothing to eliminate the algae. I am draining the pool, and as the green murky water recedes, I can see black algae (concentrated on the steps). What's the best way to get rid of the algae? My pool has a light blue quartz surface. Is power washing OK? Is a stainless steel brush OK? Can I rub the black algae spots with a chlorine tablet without bleaching out the blue surface of the pool? How thoroughly do I need to remove the black and green algae from the surfaces before refilling and SLAMing the pool with liquid bleach? Thanks for any help you can provide!
