I am ready to give up on being a pool owner. My pool was the prettiest blue and within 3 days it was green. I was told it is because I left the solar cover on. Now it is a thick dark green. I have shocked it over and over. I have added chlorine bleach and it is still saying my FC is low. I am now told I need to flock it or I will never get the algae out. I have spent over $100 in chemicals. I really had hopes of celebrating the 4th in my pool.
