Hi I'm new to this. My previous levels were FC - 3, CYA - 60, PH - 7.3, Phosphates - 100, CH - 280. These levels were at the end of my Green to Clean cycle. I am now on day 4. Yesterday things were looking better. Algae was gone except for a few dusty areas. I SLAMMED the pool based on the recommendations from poolcalculator.com. I used about 5 gallons of bleach to get the FC levels to a 24. I backwashed, brushed and vacuumed the pool. Clarity in the water was coming back. It rained last night. This morning, the algae is returning. Now what? I just don't understand what more I can do. Please help. I have been dealing with this for a month!
