Pool closer ran amuck with copper algecide

[stevenl241]

Hired someone to close my pool and without asking me they dumped in 32oz of copper based algecide before putting the cover on.
Now I'm worried about copper staining over the winter!
Should I be worried?
Should I reopen the pool now, completely drain and refill and reclose with poly algecide?
What if I just wait til the spring and reopen then?

Thanks in advance for any advice.

32 oz, do you know what % copper the algeacide is? If so we can figure out what the copper level is now, and predict if it's high enough to cause problems.

Yes, the bottle was labeled "51.6% ethanolamine complex, equivalent to 7.41% elemental copper."
So, I think they added 0.62 ppm copper.
Danger zone for copper staining over the winter??????

Thanks,
Steve

Is it worth reopening and draining now?

Just keep pH under control. Higher is the pH bigger the risk of staining the surface. Best if you lower the pH in the 7.2 - 7.5 interval. Did he lower the water level? If yes the spring opening will dilute the copper concentration. Some copper will be lost in winter together with the dead algae and some more will be lost in backwashing in the next summer. Risk of stains is spall if copper concentration is smaller than 0.5ppm. You are close to the safe limit.
