This morning I found many of the remnants of all the fireworks that were blowing up in our neighborhood last night in our pool.

Besides the chunks of cardboard, there is a lot of brown powdery stuff on the bottom that I swept up and there was one chunk of cardboard that still had a lot of brown powder in it that dissolved into the pool when I picked it up.

What's this going to do, if anything, to our water chemistry? Chlorine is fairly high right now, ph is good. We can't switch to salt for 16 more days since the stonescapes pebble plaster is still curing.
