Mustard algae - first time infection

[Simmons99]

BEFORE you shock the pool - you have METALS in your water - it would be best if you get the metals OUT of your pool prior to shocking. Getting a metal sequesterant prior to shocking might be the best option.

Check out the metals forum and algae forum.

I'm not sure that's enough metal content to be any factor. Quite frankly, I've never seen posted on this forum the level where metals become problematic.

If it were my pool, I think I'd shock it to kill the algae and then deal with the metal issues if they appear.

Handy, that copper probably got there by adding something to your pool that had copper in it (at some point in time). Generally, I would discourage you from using anything with copper.
