any advice would be great. Before reading your last reply I shocked with 10 pounds of cal hypo yesterday.

This morning I have visible powdery algae on all horizontal and sloped surfaces. The test strip turned dark purple immediately going into the water. I have never seen such a saturated purple color before. I am pretty sure the chlorine is high.

could this just be pollen and I am flipping out for no reason?

I vacuumed the accumulations of algae. Then I brushed all of the flat surfaces. I am going to brush the sides later this afternoon.

What about turning off the pump to let everything settle and then vacuuming tomorrow morning?

my most immediate problem is that I need results quick because I am going out of town on Saturday and will be gone for 2 weeks. the rest of the family can follow simple instructions, but anything complicated......
