I like the sound of the rippling water, too, but that may be what it making your pH rise. Get the pH down to mid 7s range. Then, keep the jet aimed downward most of the time unless there is a lot of floating debris that you are trying to direct into the skimmer.

To lower your pH, you can use a little muriatic acid but please read the info at this link first:> http://pool9.net/muriatic/
What is your TA, by the way?

Before deciding to raise your CYA up any higher, try using larger doses of bleach as I mentioned previously. The best time to test and add bleach is in the evening after the strong sunlight is off of the pool. Each evening when you test, add enough bleach to take the chlorine back up to 6ppm.
