Greenish Stains in Bathing Suits

[brandonc14]

First time pool owner here and our pool was just put in a month ago so excuse the ignorance. I've searched the site and it looks like copper in the water is the most likely cause here of the green stains on the white swimming suits. My water was tested last week and had a copper value of .2 would that be enough to cause issues?

I believe it's related to sunscreen so for reference we are using Up&Up brand from target SPF 30 spray version.

Since that test in the screenshot my chem balance has changed with additions and SWG changes.

Using TF-Pro Salt today:
CYA: 30
FC: 3.5
TA: 90
PH: 7.9
TA: 90

Thanks for the help.

Welcome to TFP.

There are chlorine products and algaecides that contain copper. We recommend that none of those products ever be used and to always check the ingredients carefully. Never use any pool product labeled "blue" as that is a code word for copper.

Once copper is in the water the only way to get it out is to drain the water.

The accublue/spintouch may be off by 0.3 at 0.3. So a 0.2 may be a 0.5 and vice versa.
If youre seeing visible staining, i'ts eveident the level is too high IMO.

Thank you both for the insight. Just got my fill water tested and it does not have any copper so something has to have been added is my best guess. Had the pool serviced for the first few weeks so chasing down what they added.

From a lab or the pool store ? Again, the pool store is terrible. They recently told someone i was helping that their fill water was bad but the pool was fine. The pool was green with iron so they at the very least torally botched one of the two back to back tests. They may have botched them both for all we know.
