This may have been answered before, but I'll ask anyway.
The general TFP guidance is that I don't need to super chlorinate if I keep chlorine above the min level for my CYa. Yet, every chlorine product you buy in the stores will give you the "once a week / superchlorination" recommendation. Is that simply to make you use more? Is that simply age-old wisdom that the industry refuses to let go? Is it being "overly cautious", since many people aren't patient enough to check chlorine once a day, and better to be safe than sorry?
Similar question...I asked the guy at pool store, "What do most people do to chlorinate their pool?" He said it was the trichlor pucks. If that's the case, do all these people end up draining their pool like I did? Do they eventually have a big algae problem that forces a draining? You'd think you'd hear about more problems if everyone was doing the trichlor thing. (And maybe they're are lots of problems, but I don't know about them.)
It certainly makes it difficult as a consumer / pool owner.
