I searched this topic but couldn't really find a discussion about it so I apologize if it's been discussed before.
With the summer in full swing my kids (ages 11 and 14) are continually being asked to swim parties at their friends house(s). I'm fairly confident most of the parents don't use this method of caring for their pool.
My concern is the water condition (mainly the FC) of these pools. I've talked to one of the families and they use the test strips and add 1 gallon of chlorine once a week! They use the pucks but in a 18,000 gallon pool there is no way a once a week bleach add along with pucks can maintain a healthy FC level. (can it?)
Somehow their water is clear so they assume all is well.
My question is, do I allow my kids to swim in friends pools when I don't know the condition of the water? Perhaps I'm just being a worrisome parent...
