YOWTCH!!!

You'd better take a sample to the pool store and post numbers.

I suspect you are having extreme metallic staining, but I could be wrong.

Copper sulfate is NOT a good thing to put in your pool.

But if your hubby won't listen, there's nothing we can do to help.

You may have to drain and scrub your pool.--you can't drain it all the way, either--you must leave 6" to a foot of water.
