Is it normal for chlorine consumption to go through the roof when treating your pool with Black Algea Killer?

If the Leslies stuff, copper AND ammonia! A double whamy. Lots of chlorine will be needed to remove that vile stuff.

Yes, it’s Leslie’s Black Algea Killer. I had something from before I started using liquid Chlorine and noticed some of the Black Algea had returned, so I gave it a treatment and my Chlorine level went way down.
