Although my head is spinning, I realize this is a great place to learn. I thank everyone in advanced. So here it is. Family of 6 here and 3 of us developed a what my wife calls a rash, lasted a couple of days and is gone. She thinks it's the pool water. I opened the pool 10 days ago to crystal clear water. Brought up a sample to pool store, was told everything was fine. I have a 24' above ground pool, and I use " enjoy once a week" for maintenance. I've used this the past two season with not one problem. After the rashes developed I took another sample up there was told everything still looks good.
FC .3, TC .1, ph7.3, Alk 77( just added alkalinity plus to get it up) stabilizer 72. I asked about bacteria after my wife went online and read horror stories. They said I would know if there was bacteria in pool (coloration and slime). This rash can be from anything inside or outside of pool. Wondering if there was a way to test for it. I'm still learning and reading here. How can I eliminate cause of rash being from pool. One more thing any recomendations for test kit. Thanks
