I need some help with what I need to do to get rid of this algae. Our pool has been cloudy for about a week and a half. We've been using bleach to keep the chlorine level in check. Then the it started dropping and we've been playing with bleach to keep it up.
I haven't been in the pool this year until the other day when I realized that we have black algae on the liner *above* the water line.
My husband used to pool brush on it then the liner print started to come off! It's not like he was cleaning it with bleach, he was using just the pool water. I can rub it off with my finger.
We couldn't figure out why it was above the water line. The pool guy came out, he'd never seen it before, he's going to talk to the liner guy. I had a light bulb moment earlier where I think I figured out why it's above the water line. We have an automatic pool cleaner that crawls up the sides of the pool and spins above the water line. I think it is spreading it.
I'm also attaching a picture with some clumps that show up after a day. Not sure if they are algae clumps. We live in an area with new construction and a swampy retention area behind us.
Lastly, I'm attaching a picture of the stairs because my husband swears he completely cleaned off the stairs within the past week.
I know I need to SLAM my pool. I'm not sure how to get rid of this black algae.
1) Do I get in the pool and scrub it off?
2) OR Do I scrub the edges from outside the pool?
3) Do I need to use a cleaning agent to scrub the algae?
4) Should I contact the liner guy about the fact that they pattern rubs off after regular brushing with the pool brush?
My latest numbers using the TF-100 test kit (*note I gave a SWG):
Thank you in advance for any help!
