Thanks for the replies.

I made a typo, we do use chlorine, but not bromine or bacquacil.

The pool is approximately 12,500 gallons and we have a Hayward side mount sand filter.

We have what I call a leaf net, in that it is a larger bag, but I do not believe it has a squeegee edge on it. I'll look for one of those as well as the liquid chlorine and vacuums for leaves.

Also, I will take the water to be analyzed and post the results.
