Stains on Finish

[vic49]

I have Wet Edge Primera finish plaster in the pool. The pool is 15 months old and up until the last week or so has been fine. These spots have appeared in 3 different places and I have no idea how or why. The pool is in a screen enclosure. Any ideas what is causing them and how to get rid of them? All three are ranging in size from a nickel or dime.

It could be fertilizer, or stainless steel bristles that got caught in the pebbles during startup. They usually take a while to break down and start rusting. Have you tried vitamin c tablets?

No I haven’t tried anything yet. I just noticed them. They sort of just appeared out of nowhere. It’s screen enclosed so I’m not sure it would be fertilizer. The plaster is polished smooth Primera Stone. How do you use Vitamin C tablets in the pool? Is that something I just get over the counter? Any particular kind of Vitamin C tablets?

Just regular over the counter vitamin c tablets. Crush them up and put them directly on the spots or in a sock and lay the sock on them.

Ok thanks. That’s going to be tricky with one of them being on a vertical surface and I’ll definitely have to turn the IFCS off.
