Thanks! I think I'm going to leave the pH until my CL levels come down enough to get a good reading. Right now, as soon as I mix the test it's a dark color looking like the ph is off the chart... then after 3 or 4 seconds it fades and looks to be about 7.2.

I started fighting the algae yesterday morning (I found the bottom of the pool covered in a light yellowish brown "powder"). After vacuuming everything up, and brushing the sides and bottoms, the pool was looking really cloudy in the deep end. It looked a bit better this morning, and right now the water is sparkling again. I'm going to keep it up until tommorrow, then when the CL levels come down again I'll deal with the pH because I have no idea what level it's at right now.
