Easy come easy go. His pool will be green before yours, I'm sure of it. You are on the straight and narrow path.
Are you vacuuming the dust away and it's recurring? Your pump will not remove sediment on the bottom of the pool. Vacuuming is a necessary evil. Though not so evil for me since I bought a robot!
I have a Polaris P39. The sock is collecting some of the sediment. However, when I remove the cleaner from the pool you can see blooms escaping the sock.
I do not have a mulitport valve so I’m not sure how I can vacuum. I have a back wash valve that slides up and I spigot along the pvc. Can you recommend a vacuum for this type of setup?
I plan on on installing a multiport valve but probably won’t tackle that project until next pool season.
