Our next door neighbor has an Intex that he puts up every year and every year it goes green. He drains, refills, etc several times per season. This year it went green within 10 days and he's letting it stay that way because his kids and their friends don't mind it. (I have given him this website, I have taken over my kit and tested his water, I shown him the whole 10 minute process of getting my kit, testing FC, CC, and pH, adding chemicals, and putting kit away). He says he'll learn it someday. But apparently not this year.
This year, my kids are older and now play with his kids. My kids aren't allowed to go to his yard, though, because I'm not ready to let them swim unsupervised like his slightly older kids do. So.......... now his kids and their friends swim all day in his green pool and when my kids get home with me after work, his kids and their friends want to come play with my kids in our sparkly pool.
Tonight is the first night this inevitable scenario played out and his kids are now in my pool, presumably in the same swimsuits that were in his green pool. What is the risk to my beautiful water? Do I just test like normal and only bump it up if I get a bunch of CC, or should I assume I have an issue and bump it up slightly over normal target, or do I need to take it to shock? This will likely recur several times per week.
My numbers as of last evening (pre-neighbor-invasion):
Temp tonight 89
Salt about 700
Thanks for any help in walking the line between letting my kids play with nice kids whose dad keeps icky water, and protecting my beautiful water.
