I am using test strips and they appear to be able to read down to around 6.6 ph The color is kind of between 6.8 and 7.2, if I had to favor one or the other via color I would favor 7.2.

After it all started I tried a defoamer for a couple weeks, and that will for a day or so stop it.

I tried clarifier once a week, for about 2 weeks. Did not seem to help.

All products were from pool stores.

I have been aerating via pointing the jets upward for the last 24 hours, after reading the interesting post on carbonates and it seemed to be helping a little bit as of tonight.

The swim suits have not been washed in soap now for 2-3 weeks and no sun screen either for at least that long.

I should mention we live near Minneapolis, MN so it is cool now, average daily temp around 60 to 65 degrees, and I kept the pool around 75 degrees.

Thank you all for your help.
