    low or non-phosphate scale-stain product

    In this article here:

    http://www.mcgrayel.com/files/Phosph..._and_Myths.pdf

    and in this discussion:

    http://www.troublefreepool.com/phosp...em-t16805.html

    It states one should use low or non-phosphate scale-stain product, are the Trouble Free Pool's recommended sequestrants of this ilk?

    If not is it still ok to use them or should one put phosphate remover in the water some time after they are used?

    Thank you.

    Having some phosphates in the water is not a problem at all. While eliminating phosphates from the water can slow or stop algae growth, it doesn't protect you from bacteria or viruses, for which you need chlorine. Chlorine alone completely stops algae and bacteria and viruses, so there isn't much point in spending money on phosphate removers when chlorine does everything you need done for less money and more simply.

    All of the best sequestrants contain phosphates.
