Terrible green algae problem. Appeared almost overnight...okay...maybe in 48 hours.
Wife has dropped $450 at the pool shop. Still GREEN!
She went back & had water tested today
pH is 7.4
Alk is 90
FC is 15 (we shocked the fire out of it!)
CYA is 77 (this is too high)
Calcium Hardness is 240
I have vacuumed the pool 6-7x in the past 5 days. I have brushed the walls at least 15x in the past 5 days.
From reading other forums, I know my CYA level is a bit high. But it seems a 15 FC level should still be able to attack the algae. The pool store recommended that we buy a flocculent. So my wife just bought it. Tonight we will lower the pH a bit, add the flocculent, recirculate the water & then let the flocculent settle. Then we are supposed to vacuum the pool again. I've had this pool for 17 years. Never taken more than 48 hours to clear up any problem I ever had. The pool store called the chemical rep & he asked if we had any commercial fertilizers sprayed near our house. As a matter of fact, about 150 feet from our pool is a giant hay field that had fertilizer sprayed about 3 weeks ago. Not sure if that's part of our problem or not.
Please tell me I'm not the only one!
