I had some algae grow recently. I kicked butt my first summer with this pool, then I wasn’t able to stay on top of it for a bit and some algae began.
So I SLAMmed, and after a week of removing light enclosures, scrubbing everything, removing skimmer flaps, scrubbing stairs, etc. I passed the OCLT two nights in a row.
Thanks for all your help in from thread: OCLT affected by cold air/warm water?
So here is what I noticed today. I have fiberglass stairs and a vinyl liner. Between the panels that hold the liner to the stairs and the pool wall, there is the liner and some liner lock. I noticed that there was some algae between the liner lock and the liner around the stairs enclosure. I took a toothbrush to it, and ran a dull putty knife in in the small space between the liner and liner lock, and green came out. It wasn’t much much, but it was there. It’s a very small overlap between the liner and liner lock.
So my questions, if you would be so kind as to continue educating me:
1. Is that normal? Is it ever normal to have “some” algae? Is that just inevitable, and your FC is keeping it at bay? Or can/should it be killed?
2. Any other tips on how to clean that area out?
3. Does this bely a bigger problem? Do I possibly have more algae around the stairs somehow that I can’t get to?
4. I am still at SLAM levels. I plan to keep it there for a few days. I even did the “mustard algae slam level” for 24 hours. Should I just keep up the SLAM for awhile, even when passing the OCLT?
5. Can I close the pool knowing there might be a bit of algae in areas around the stairs I can’t get to? I plan to close after the temp has dropped below 60.
Thank you!!!
