Maybe I should talk my husband into just converting to a SWG...we saw them earlier at WM and he said we would get one next year. If I tell him that I am going to have to drain more water from the pool though and that a SWG would work at that CYA level he might be convinced! LOL! And then I will tell him I have to have a NEW test kit because strips don't test SWG! HEHE
