ok I appologize and can give you some real help here! If the kids hair or scalp is still green read this post (my reply)

Test strips just won't do it for testing a pool that needs to be balanced. Go to walmart and get their 6 way or 5 way test kit that will test chlorine, pH, alkalinity, calcium, and CYA (stabilizer). It costs around $15 dollars and run a set of tests and post the resutls. You can also go to a pool store that does water testing with reagents ,not strips, and post those results if you like. Most pool stores can also test for metals so ask them to do so if you choose this route. Don't buy anything they recommend at this point until you post the test results.
Don't let the kids back in the pool until you get the water under control!

Also, if you can let us know EXACTLY what products have been put into the pool and if possible how much. It sounds like it was overdosed on copper!

Once again I aplogize but after reading through the thread a second time and seeing the winking icon it just seems a bit strange! No hard feelings?
