How often do you shock "poll"

[poolrx]

Hope its not inappropriate to ask this in this thread. I know you shock to get rid of CC and bather waste, but is it just "pool store hype" that you should shock every week? It really threw me for a loop to find how little you guys shock.

Thanks

Yes it is hype and revenue. I also shock very little only when I open and close the pool and if CC is over 0.5. I haven't had to shock in over a year(except open & close) but I do keep my chlorine around 5ppm.
