Help! 911 - algae showing up

[sw_stupid]

Okay, lost here. I started shocking. Checked it at lunch today using OTO test (in Ben's kit). It went dark yellow with one drop of reagent. So by the time I got the fifth drop in, it was YELLOW. So I diluted it with 4 parts tap water (checked it - no chlorine). Gonna multiply my result by five. Result barely changed from clear. So I did it again with 3 parts tap water. Exact same color. I don't want to have to use all my powder testing all day while I shock. So is there anyway to limit the number of drops it takes to perform the test? Example: put it one drop and then multiply result by five? Just a thought 'cause I'm at a loss here. Pool is still cloudy with no CC. (this is very depressing, just when I thought I was gettin it - guess the pool wanted to remind me how ignorant I am.)
