Yea I have wrote off trichlor and dichlor, Sticking to the bleach. Do you think it would make sense to drain more water to get down in the 30 to 50 range for cya. It takes alot of bleach to shock a 30k gallon pool to 20 ppm. I am thinking I would like to drop my cya so I can lower my fc level to around 4 or 5 ppm. Also I run my pump about 10 hours a day. I have a Hayward s244t sand filter with a AO Smith st1102 1 hp pump, two 1.5 returns one in the deep end and one in the shallow. 2- 1.5 skimmer, and a additonal 1.5 side intake in the deep end. Does this seem like enough run time for the pump?

Again thanks.
