New pool owner here (came with house) small 15x30 oval above ground. Drained and cleaned the pool, filled in march. Had no idea how pools worked. Got pool stored. CYA high (100+) by the beginning of june from floating tabs. Drained a little over half. CYA now around 55. Now following your method for liquid chlorine. Water feels better looks clearer.. Thank you guys! One weird thing is every time i do a CC test CC turns up lower than FC. possibly bad reagent?? Im using a k-2005 test kit I will be getting a fas-dpd test soon. Yesterday was 114 degrees and I lost about 4 ppm FC. Pool is in the sun from sun up until about 6pm.
