Hello, we have had a pool for 6 years now. For a few years we had a pool service taking care of it, 3 months ago we start to take the maintenance ourselves. A few weeks ago the pool started getting green and greener, the test stripes results were nothing out of the normal. I took a sample to Leslie's pool Service, CYA 240, (range 30-99ppm). The guy recommended using their expensive Bi-Active product, plus the reviews were not good OR draining our pool 2 feet and refilling the pool with fresh water and the run the pool filter 24 hours, and the repeat process 2 more times.
Does this sound right? If so is there any other steps that should be done?
Should I tried to brush off the alege?
Should I add bleach to the pool each time the pool is refilled?
Please an help would greatly appreciated.
