I live in the North East and it's that time of the year again.. I was wondering if I am wasting my money by putting in winter algaecide. I normally just make sure the pool is balance and then add a winter algaecide and let circulate for a couple of hours prior to covering..
I have read the a lot of pool owners just super chlorinate or shock their pool prior to closing and that's it. Other will sometimes add a metal treat to try to sequester trace metals and inhibit some potential staining over the winter.
Thanks in advance
