Hi! First, thank you so much for all of the info on your website. I feel so much more equipped to deal with our pool than before. I'm in the process of getting our pool back in order after under-chlorinating it over the winter. I would like to go to bleach and borax when needed to up the PH (ph was extremely low but now at good levels). Last year, I dealt with some staining and green hair issues and realized that I had been using an algaecide recommended for mustard algae that perhaps had high copper/metals? Would that make sense? If my pool still has a high metal reading after adjusting the PH, should I use a metal-out product? I've learned the hard lesson that under-sanitizing the pool (which has a sand filter, btw) is a HUGE no-no so hopefully will not be dealing with the algae problems of before but would like to know how best to deal with any remaining metals issues. Thanks so much!
