I added CYA Saturday and my ph dropped to 6.8. Should I wait to raise my ph? Also, the cya made my pool a little cloudy, but my pump isn't working properly either. Is this normal? TIA

It is common for CYA to lower the PH. You should raise it back up soon. It isn't good for the pool equipment/liner for the PH to be below 7.0.

It is not common for CYA to make the pool cloudy.

Don't worry about the alkalinity too much, yet. The two best ways I can think of to raise your PH is to:
1. aerate: run waterfalls or some kind of water that drops into the water to create bubbles. This will aerate your pool, raise your PH over time (check every 12 hours), and not really change anything else.
2. Add 20 mule team borax. This will definately raise your PH, add a little borax (good for preventing algae), and increase your TA by just a little bit.

If you post specific test values from a reliable test kit, like Taylor K 2006, you can get some additional help.

I have the ones from the pool store...

Saturation Index -0.96
pH 6.9
cya 16
Adjusted total alk 83
Calcium Hardness 65

Everything else was ok..

What is the saturation index? In the analysis section mine said corrosive...

The saturation index tells you how the water will react with plaster surfaces (plaster is also present with pebble, tile, stone, etc). If you have a plaster surface you have a problem. If you have a vinyl liner it doesn't mater if it is negative but can still be a problem if it is too high positive.
