Hello TFP
I have been reading TFP materials for the past few months and have been dipping into Pool School. Thank you all. You all seem waaaay smarter at pool care than i am or ever will be. I have been trying to SLAM and then dunk myself. I swim about 4500 meters in this pool each day, that is. The SLAM seemed to work, and then the algae returned within lass than 36 hours. I wipe and rub and sweep and use a long brush and dive down with a scrub brush more than once a day, and the ring returns, an olive-green thick algae ring where the pool becomes deeper, all along the sides and at the deep end. This is a 1962-built, old, in-ground pool, 12,000 gallons, shallow with steps at one end and approx 9 feet deep at the deep end. We leave the pump on for 8 hours/day, and i have been wondering if we should have it on for longer? Recent CYA measurement has been radical, as high as 180. I cannot drain the pool--city rules. I let the water level go down on its own by slightly more than a foot and then refilled with hose water. The CYA remains about the same, 178. In the meantime, post-SLAM and post water rise, i have found that the pH has descended to slightly above 7.0. Before the SLAM and the water lowering/raising, the pH was 8.2. This is wild. I accept anyone's advice, and please do not tell me that i am merely inept at caring for my pool? Thank you all.

they tend to get it more wrong than right..............they think with their bottom line of selling product where TFP thinks with the science and MANY years and pools that we have used to perfect our methods.
