There is a screw at the 12 o’clock and a metal plate against the liner behind the metal rim of the light. Hard to get a good face on picture
I had a feeling this would be the answer. Thanks for the help!
Rescrubbed the lights. Skimmers scrubbed. Main drain covers removed and scrubbed- nothing slimy.Scrub behind the light again.
Did you remove the main drain covers and scrub in there?
Did you scrub the skimmers?
Did you remove the weir doors and check for algae.
You are a SLEUTH...gotta find it!
You need to inspect the foam, often they are filled with algae...Remove the weir doors? It’s not enough to scrub them attached?
There is no need to buy new weir doors, the foam can be cleaned in a 10:1 Water:Bleach solution and scrubbed. The foam is a simple replacement with some foam and hot glue.Probably just best to replace the weir door.
What do you mean by behind the steps? We have scrubbed the seams of the steps really well. Those don’t come off so they? How do I inspect the bottom of the pool cover?Probably just best to replace the weir door. What about behind the steps below the ladder? And do I see a pool cover? That can be a source if you've been using it and it lays on the water.
You can't scrub behind the steps. You should scrub the perimeter of the steps where it meets the liner.What do you mean by behind the steps?
Yes. That’s been done several timesYou can't scrub behind the steps. You should scrub the perimeter of the steps where it meets the liner.
