for how long to let the pump run after adding each chemical? For example, I know to let the pump run for 24 hours after adding CYA. What about after adding small amounts of chlorine? Large amounts of chlorine (for shocking purposes)? Acid, baking soda, etc? I guess it's different if you're fighting a problem, like algae or high TA for example. But I'm asking about just "maintenance" doses of chemicals.

I usually test my water between 4-5PM, and add any chemcials needed around 7PM. The pump is usually set to go off at 8-8:30PM. I'd rather not run it overnight if I don't really have to.
