I just read this in another thread. I've never heard of this before, but I can understand why it sould make sense. Should I be doing this to get the green out of my pool ASAP? Can someone please explain EXACTLY where the panty hose go?

Also, what's SWG?

I'll try & post some test results, but I don't trust them at all. Stupid dip strips . I've read here that the pool store guys do the same test, so I don't really trust their results either.
