Costco 有大盒的aqua chem pool shock 在卖。看说明书建议每周用。可是从 troublefreePool.com上看似乎不建议常shock。 请明白人帮忙答疑。谢谢!

I shock my pool every 3-4 weeks. my automatic chlorine feeder takes care of the rest (there was a debate before on using feeder/tabs due to CYA, though, tabs work fine for me because I close/open every year).
