New pool, new owner

[KAsarge]

Hi! I’m attaching pics and test results. My taylor kit provides the same results as the pool store so that’s good news!

With my pool, I feel like the plaster job was terrible. There are huge streaks and stains from the hose used for fill up and stains where it looks like the spilled something. Those aren’t actually my concerns with the job. Instead, over the past few months (my pool was finished and filled in March of this year) I’ve noticed white spots appearing. I stay on top of my chemistry and CSI.

The pool builder said it’s scaling. I tried brushing it with acid and it did nothing. It also doesn’t really feel different than the surrounding plaster. Even after showing the PB my test results he still says it’s scaling.

Any ideas?

Welcome to TFP! I'll tag @onBalance who is one of your plaster experts on the forum. He might have some feedback for you. In the future however, please post your own Taylor test kit numbers. We have little to no faith in pool store testing.

Also please update your signature. It's currently blank. See my signature as an example. It helps tremendously as we analyze your questions.

I’ll add some more pics to show the plaster job in full context. First shows where they laid the hose for fill and the stain it caused. Second shows what looks like some sort of splash stain and third shows three large streaks. I know imperfections are part of if with darker colors but yeesh, seems it’s a bit more than what I would expect. These things make me question if the white in my first post is really scale and not just a bad plaster job.

Shame about all that trouble. @onBalance will respond next time he hops on the forum.

Please read the below post.
There are a number of things that may be involved with your colored quartz plaster turning white in streaks, spots, and other patterns. One likely cause is that a poorly performed acid wash was performed on the new plaster prior to being filled with water.
Also, out-of-balance water that leads to "scaling" will generally do so with a uniform and consistent manner throughout the pool, not in random streaks and spots.

Why Colored Plaster Turns White

Plaster colors can fade or turn whitish for a handful of preventable reasons. First off, scale can be deposited onto pigmented plaster surfaces by out-of-balance pool water. As is widely known, calcium scale makes the surface rough and turns it white, and acid washing is often the remedy...
