Hello! We went on a trip out of town and I left a couple tabs in while we were gone. Came back to find these blackish green spots on the floor of the pool/steps. Figured it was just some algae dust or organic matter that had settled but it does not brush easily away. We have a vinyl liner so I’ve read that it’s unlikely to get black algae? I have scrubbed at these spots though and they really don’t dissipate like I’d expect.
Current deets:
22k gal IG pool
Vinyl liner
Robotic dolphin vacuum
Taylor test kit readings:
Ph 7.8
Tc/fc/cc 0
Ta 50
Cya 30
Obviously beginning a slam now (with LC) -and will continue to brush away. Just wanted to ease my mind a little/start tackling it if it is black algae. Thoughts??
