So just for fun (no flaming!) I Googled "Clearing a Green Pool"... just to see what kind of information is out there.
It's all really, really bad information. Things that will ruin pool and filter equipment!. I was shocked, really shocked, at the amount of bad information that's out there. I can only hope that pool owners will find our site and read Pool School....
Yesterday I was in Walmart buying a floater, and the Arch chemical rep was there! stocking the shelves (they were relocating the entire display to a different area of the store). He asked if he could help me find anything. I asked if "HTH makes any tablets without copper in them?" (I already knew the answer, I was just messing with him)
He grabbed a cannister of cal-hypo tablets and said "these are good - no copper, put 2 or 3 in your skimmer and 2-3 in the floater and that's all you'll need."
I said, "That's all i need? Really? But there's no CYA in them. What about CYA?" He said "What's CYA?"
I swear this is true. This really happened!
I Said: "Stabilizer." "Oh, you really know your pool chemicals, don't you." Me: "Well, yes I guess I do, but I had to learn the hardway. And I don't want no stinkin copper in my pool!"
"Well, here just buy this jug of stabilizer instead. Then you can use these here tablets." Which I suppose I could have gone that route but I wanted trichlor tablets (Once my mind is made up I'm stubborn that way. I just want to have the floater and leave the solar cover off for a few weeks.) Plus aren't cal-hypo tablets really gooey and messy? Thought I read that here. He also said that the tablets won't dissolve in the skimmer if the pump is off...
"Well, where ya gonna find that?" (trichlor without copper). Me: "The Pool Store".
"Well, you know you'll pay more there." Me: "yes, but I won't have the copper." "What's wrong with the copper. It's an algaecide you know." Me: "Yes, I know, but it also turns hair green." "Green? Why, is your chlorine very high?" Me: "No, my chlorine is normal but blonde hair turns green from copper. I know this from past experience using the pool frog." "Whats a pool frog?" Me: "It's an ionizer. I have to get going, thanks. Have a nice day!"
Anyway just thought I'd share...
