Of course after, the kids nag & nag & nag him to buy a pool as well Days later he calls me up and asks about pools, costs, maintenance, etc ... So he gets a 4000 gallon rectangular AG pool. He's got a lot more question now which i expect, and im more than willing to answer any and all. He's very intelligent and capable of reasearching his own, but meanwhile time is running with his newly filled pool, and i got him to a good start by telling him about pucks and CYA. I told him to read the labels of every chemical before applying. Well I guess I overwhelmed him with info (ounces, cups, lbs, gallons, PPMs, pH, CYA, alkalinity....) in such a short period of time that he pours the ENTIRE gallon of liquid chlorine in his half filled pool. So now even im in panic over the phone, I asked him why the whole gallon? And he thought that was what i said. I calculate his pool to be about 52 PPM of chlorine, so i told him to just wait out the chlorine not to swim in it yet and he says ok. I call him up 2 days later to check up on the pool and he says they just went swimming... Holy !@#$ I guess i didnt clarify how long to not swim in it, so i blame myself again!! Well this past weekend he invites us to go camping for the weekend, and im thinking in my head, you have a newly setup pool that you're still learning about, and after our hour long conversation about getting the pool water balanced you're going to leave for 3 days?? But then i also think with the sky-high chlorine it may be just fine. So what do you guys think? He is very mechnically inclined and internet savvy, and I have pointed him to this website, I dont know if he has visited yet...Anyway, just sharing a story because I feel guilty.
