I woke up this morning to find YET AGAIN... algae blooming. I tested my water this morning and here's what i got:

Hardness - 250ppm
Chlorine - 5-10ppm
Free Chl - 5ppm
pH - 7.8
Alkalinity - 80ppm
CYA - 30-50

This test was done with AquaCheck Select test strips. So what gives? What am i doing wrong that algae just keeps reoccurring, even with sufficient Chlorine and pH levels? I might also add that the pool was beautiful when we moved in approx. one month ago. The pool does have a Chlorine feeder on it, but i've been trying to keep with using bleach to keep my CYA levels from getting higher while I get this thing in order.
