Hi Richard,

You are so kind to help me. I may have been unclear in the previous post about the loss I experienced. I started the day Sunday at 15ppm (it held overnight Saturday) and ended the day Sunday with 10ppm.. a 5ppm loss.

I added Bleach last night to bring it to 18ppm ( I also put one trichlor puck in the skimmer)and checked this afternoon. The chlorine is 14.5ppm. It was not as hot today, but sunny almost all day. I added another 96oz of 6% bleach (usually gives me 3ppm rise) a little bit ago. I know when the CYA was about 60, I did not have as big a drop daily. You did a survey last summer and asked me for my numbers ( I don't remember them now)

I am nearly positive this is some sort of dirt/pollen. It brushes away very easily, just the momentum of the water will disturb it. I cannot find anything on the walls or ladder. I have run my fingers under the ladder step and found nothing.

I am reluctant to add more stuff to my pool because one of my 4 legged children drinks out of it! I hate to even use algaecide, so I am not too sure about the borate....although I realize if we had city water it would be the same thing or close to it.
